Home Secretary Amber Rudd will find out if she’s kept her Conservative majority in Hastings & Rye in East Sussex. Ms Rudd secured a majority of almost 5,000 in 2015 making a loss unlikely. But if she’s ousted it would represent a complete crisis for the Tories. For armchair politicians, there’s nothing more exciting than pulling an all-nighter during a general election. But what are the big constituencies to watch this evening, and when will your area declare its results?Here’s an hour-by-hour run down of the night. Put they kettle on, it’s going to be a long one. A Labour victory is all but guaranteed in Mayor of Manchester, Andy Burnham’s old seat of Leigh. Credit:AFP 12:30amIt will be a bit quiet on the declaration front around now, so maybe grab a power nap, or get another coffee.The result in Kettering should provide an indication of just how many Ukip voters are switching to the Tories. The incumbent Tory Philip Hollobone took the unprecedented step of signing an election pact with the party after saying he agreed with the party on Brexit, HS2, axing foreign aid targets and a burka ban.Ukip agreed not to stand a candidate against Mr Hollobone, who has agreed to meet with Ukip party members every three months if re-elected. The Ukip candidate won almost 8,000 votes in 2015 so a strong performance for Mr Hollobone will be welcomed by Tory HQ as evidence of a Ukip swing. KetteringSwindon North 1am First marginal seat of Nuneaton, in Warwickshire is expected to declare around now. David Cameron said he knew the Conservatives had won when the result came in for this bellweather seat in 2015. We’ll also see the first London seats come back, including Conservative stronghold Putney. Secretary of State for Education Justine Greening is expected to retain her lead here.Meanwhile, the first results in Newcastle will show whether Mrs May’s tactic of repeatedly visiting the region to woo voters has paid off. It’s Labour’s heartland, but strong showings for the Tories could well spell doom for Mr Corbyn’s chances of winning the keys to Number 10. Antrim NorthBatterseaFoyleNewcastle upon Tyne CentralNewcastle upon Tyne EastNuneatonPutney 1.30amThe Conservatives have realistic hopes of winning Darlington which is currently held by the Labour shadow Brexit minister Jenny Chapman. She won the seat in 2015 with a majority of just over 3,000 with the Tory candidate in second place. A defeat for Ms Chapman would be a big loss for Labour – the party has held the seat since 1992. Meanwhile, Dr Rosena Allin-Khan will be hoping to win Tooting, the south London constituency she won in 2016 in a by-election after Sadiq Khan resigned to become mayor.BroxbourneDarlingtonLagan ValleySwindon SouthTamworthTootingTyrone WestWrexham 2amDeclarations start to come in thick and fast from constituencies across the country, including three-way marginal constituency Thurrock which the Conservatives won in 2015 by 974 votes over Labour, with Ukip just 438 votes behind. 11:30pm – 12pmThe Tories are hoping to hoover up votes in the north of England with their stance on Brexit. Some polls have shown the Conservatives are now level with Labour in some constituencies and lead among working class voters.

If you were after some 11th hour excitement though, you won’t get it from these seats. They have overwhelming Tory majorities. Devon CentralDevon West & TorridgeCornwall South East12pmPhew! These are the final three constituencies expected to declare their votes just before lunch. Labour seat Birmingham Erdington is down to declare too. Nick Timothy, Mrs May’s chief of staff, once called for the Conservatives to go through “Erdington modernisation” – pitching itself to this working class seat. Then he got to write their manifesto. Will it work? Elsewhere, former Lib Dem leader and deputy PM Nick Clegg will be hoping to hang onto his Sheffield Hallam seat which was heavily targeted by Labour in 2015. Croydon Central is another of Labour’s top targets and will be worth watching. Taking the seat would end a hat-trick of Tory wins and topple Gavin Barwell, the housing minister. Polls putting Labour at 17 points ahead in the capital suggest it’s doable.Aberdeen NorthAberdeen SouthAberdeenshire West & Kincardine Aldridge-BrownhillsAyr, Carrick & Cumnock Ayrshire CentralBanff & Buchan Barrow & Furness Bassetlaw Bath BeckenhamBermondsey & Old SouthwarkBethnal Green & BowBeverley & Holderness BirkenheadBirmingham NorthfieldBlackley & BroughtonBolton WestBosworthBracknell Brentwood & OngarBromley & ChislehurstBroxtoweCamberwell & PeckhamCannock ChaseCardiff CentralCardiff NorthCardiff South & PenarthCardiff WestCarmarthen West & Pembrokeshire SouthCarshalton & WallingtonChelmsfordChelsea & FulhamCheltenhamChesham & AmershamChesterfieldChingford & Woodford GreenColchesterCopelandCroydon Central Croydon North Croydon South Cumbernauld, Kilsyth & Kirkintilloch East Derbyshire MidDon ValleyDudley NorthDudley SouthEast Ham Edinburgh East Edinburgh North & Leith Edinburgh SouthEdinburgh South WestEdinburgh West ElthamErith & Thamesmead Esher & WaltonFeltham & HestonFolkestone & HytheFyldeGarston & Halewood Gateshead Gedling GloucesterGordon Gower Greenwich & Woolwich Hackney North & Stoke Newington Halesowen & Rowley RegisHaltemprice & Howden Hampshire North West Harwich & Essex NorthHayes & Harlington HendonHerefordshire NorthHertford & StortfordHertfordshire South West HertsmereHigh PeakHornchurch & UpminsterIpswich Kensington Lancashire West Leicestershire North WestLewisham EastLewisham West & Penge Leyton & WansteadLichfield Liverpool RiversideLiverpool Wavertree Liverpool West Derby Londonderry East Meriden Monmouth Newcastle-under-Lyme Norfolk MidNorfolk South Norwich South OgmoreOld Bexley & Sidcup OrpingtonPendlePlymouth Moor ViewPlymouth Sutton & DevonportPontypriddPoplar & LimehousePreseli Pembrokeshire Rayleigh & Wickford Richmond Park Romford Rossendale & DarwenRuislip, Northwood & Pinner Runnymede & WeybridgeSaffron Walden St Helens North St Helens South & Whiston SalisburyScunthorpe SevenoaksShropshire North Skipton & Ripon Solihull Southport Staffordshire South StevenageStoke-on-Trent CentralStoke-on-Trent NorthStoke-on-Trent South Stratford-on-Avon StroudSuffolk WestSutton & Cheam Sutton Coldfield Tonbridge & Malling TottenhamTwickenham Uxbridge & Ruislip SouthVale of Glamorgan Walsall NorthWalsall SouthWalthamstowWealdenWest Ham Weston-Super-MareWiltshire South WestWirral South WithamWoking Worcestershire MidWorcestershire WestWythenshawe & Sale EastYeovil 4:30amIf you’ve been up all night, keep going because there’s about to be another huge flurry of results, including in Mrs May’s ultra-safe Tory constituency of Maidenhead, Berkshire, where she’ll be to see the results come in. Will incumbent Simon Danczuk, who is standing as an independent, beat the Labour Party in Rochdale? The MP was suspended from Labour in 2015 following allegations he sent sexually explicit text messages to a girl aged 17, so it will be interesting to see if voters back him, or the party.The Tories believe they can make historic gains in the north east thanks to Brexit. If they take Tony Blair’s old seat of Labour-held Sedgefield, then half a dozen could fall their way in the region, symbolically burying New Labour.Other seats to look out for include Vauxhall where the Brexiteer Labour incumbent Kate Hoey will look to hold on, and Ilford North where Labour’s Wes Streeting is defending a majority of less than 600 votes. The Tories used to hold the seat and will be confident of grabbing it back. Will Caroline Lucas, the only Green Party MP, hold onto the Brighton Pavilion seat?

It’s a top target for Team Corbyn which hopes to take advantage of the party’s poll surge in Wales. Failure to do so, perhaps as a result of Ukip’s plummeting vote share, would be a blow. Prime Minister Theresa May canvasses in Richmond with Conservative candidate Zac Goldsmith.Credit:Leon Neal/Getty Images Edinburgh South’s Ian Murray – Labour’s only Scottish MP in 2015 – is in a three-way fight to keep his seat with the SNP and the Tories pushing hard. Victory would keep the party clinging on north of the border and help save Mr Corbyn’s blushes.Lib Dem-held Richmond Park is Zac Goldsmith’s chance of redemption. The Tory golden boy was toppled in a by-election last December just months after losing the London mayoral race amid accusations of dirty tactics. Winning back this seat would restart his political career. Next door in Tory-held Twickenham, we’re on the look-out for evidence of the fabled “Lib Dem fightback”. Sir Vince Cable narrowly lost in 2015, but he hopes to ride a surge of pro-EU sentiment back to Parliament given the Tories’ Brexit stance. Meanwhile, the Tories are hoping to snatch Chester back from Labour’s Chris Matheson who won in 2015 by just 93 votes. Then there’s Cambridge which is a top target seat for the Lib Dems. If the party cannot take it back from Labour, a pro-EU town lost by a whisker in 2015, they face a disastrous night. Former MP Julian Huppert is their candidate.The Tories have high hopes for Wales as it backed Brexit. Mrs May was the first Tory leader to visit the Bridgend constituency during the campaign in 20 years. To make major Welsh gains they need to take this seat from Labour.Altrincham & Sale WestAshfield Ashford Banbury BasingstokeBatley & SpenBeaconsfieldBedfordBedfordshire MidBexhill & Battle Birmingham Hodge HillBirmingham LadywoodBirmingham Selly Oak Birmingham YardleyBoston & Skegness Bradford East Bradford West Braintree Brentford & Isleworth Bridgend Brigg & Goole Bristol EastBristol SouthBristol WestCaithness Sutherland & Easter RossCalder ValleyCambridge Charnwood Cheadle Chester, City ofChichester Colne Valley DartfordDaventryDerbyshire Dales Devon North Dewsbury Doncaster Central Doncaster North Dorset South Dorset WestDown South Ellesmere Port & NestonEpsom & EwellFaversham & Kent MidFermanagh & South Tyrone Finchley & Golders GreenGrantham & Stamford Guildford Halifax Hampshire North EastHarrow East Harrow WestHazel Grove Hemsworth Hereford & Herefordshire South Hexham Hitchin & Harpenden Inverness, Nairn, Badenoch & Strathspey Kingston & SurbitonKingswoodLeeds West Lewes Liverpool Walton Loughborough Louth & HorncastleMaidstone & The Weald Manchester Central Manchester Gorton Manchester Withington Middlesbrough South & Cleveland East New Forest East New Forest West NewarkNorfolk North Normanton, Pontefract & Castleford Northamptonshire SouthNottingham East Nottingham NorthNottingham South Oldham West & Royton Orkney & ShetlandPenistone & StocksbridgePoolePudseyRichmond (Yorks) Ross, Skye & LochaberRugbyRushcliffeRutland & Melton St AlbansSalford & Eccles Sefton CentralSherwoodSleaford & North HykehamSomerset North EastSpelthorne Stockport StourbridgeStretford & Urmston Suffolk South Sussex MidWakefield Warrington NorthWells Wirral West Wokingham Worsley & Eccles SouthWyre Forest Yorkshire East 5:30amA key seat for Labour, Southampton Test, is expected to be announced about now. It is one of only a handful of marginal seats visited by Mr Corbyn during the campaign and the party will be hopeful of holding on. Alan Whitehead secured a majority of almost 4,000 votes but the Conservatives, who came second in 2015, could claw back some votes here. A loss in Southampton for Labour would spell disaster for Mr Corbyn’s hopes of victory. Mr Corbyn campaigned in Blyth Valley just days before the election, but the chances of a defeat for Labour there seem small with a majority of almost 10,000.Berwick-upon-TweedBlyth ValleySt Ives Wansbeck Argyll & ButeBirmingham Erdington Blackpool North & Cleveleys Blackpool South BolsoverBury St EdmundsChipping BarnetCorby Eastbourne EddisburyFilton & Bradley Stoke Hampshire EastLeeds Central Leeds EastLewisham DeptfordMaidenhead Mole Valley Newry & Armagh Newton AbbotRedditchRomsey & Southampton NorthScarborough & WhitbySelby & AinstySheffield Brightside & HillsboroughSheffield Central Sheffield HallamSheffield HeeleySheffield South EastSomerset North South Holland & The DeepingsSouth Ribble Staffordshire Moorlands Suffolk Central & Ipswich North Suffolk CoastalSurrey Heath Surrey South West Thirsk & Malton TynemouthTyneside NorthWeaver ValeWindsorWitney Wolverhampton North EastWolverhampton South EastWolverhampton South West 5amUkip’s best chance of a seat will be in Boston and Skegness in Lincolnshire which is expected to declare around now. Boston was the country’s most Brexit town, with 75.6 per cent voting Leave, while the Tory incumbent was a Remainer. If Paul Nuttall, the Ukip leader, fails to win then calls to resign could follow. Another key seat is Leeds North West where the Liberal Democrat Greg Mulholland is defending a majority of almost 3,000. Labour finished second in 2015. Can they go one better in 2017? The loss of a Lib Dem seat would be a crushing blow to Tim Farron’s hopes of a resurgence for the party. AylesburyBerwickshire, Roxburgh & Selkirk Birmingham Edgbaston Buckingham Cambridgeshire South East Elmet & Rothwell Gravesham Great Yarmouth Hemel Hempstead HorshamHove Leeds North East Leeds North West Norwich North Shipley Sittingbourne & Sheppey Southampton Itchen Southampton Test Warrington South Winchester6amBy this point the overall result should be becoming clear, so it’s almost time to get some rest. Caroline Lucas, the only Green Party MP, will discover if she has held onto the Brighton Pavilion seat, while Jon Ashworth, the shadow health secretary, will find out if he has held onto Leicester South. Esther McVey will find out if her bid to replace George Osborne, who stood down to be editor of the London Evening Standard, as the Tory MP for Tatton has been successful. Could the Tory surge in Scotland reach as high as Angus Robertson? Toppling the SNP’s deputy leader in Moray would be a major scalp and mean the Conservatives could bag 10 or more seats, but the bookies think it will hold. If the Tory surge in Scotland is genuine, they will take Pete Wishart’s seat of Perth and North Perthshire from the SNP. Conservative gains would fuel the argument that support for Scottish independence is waning; failure to break through, especially here, would boost the SNP.The Tories have a ‘take-out Tim’ strategy in Lib Dem held Westmorland and Lonsdale, to oust Lib Dem leader Mr Farron by playing on the Cumbrin area’s Brexit support. His aides dismiss the idea as ‘nonsense’ and the majority is whopping – but it’s still one to watch.

The seat has been held by Labour since 1937, and by Corbyn since 1983.More interestingly, we’ll find out if Labour has retained its most marginal seat in Wales, Ynys Mon, formerly known as Anglesey, against the confident Tories. The current MP is Albert Owen, but a poll puts it at one of the seats which Labour is most at risk of losing in Wales.A result should also come in for the Leigh constituency in Greater Manchester which Andy Burnham represented since 2001 before stepping down to be Mayor of Greater Manchester. Mr Burnham secured a huge 14,000 vote majority in 2015 and a Labour victory is all but guaranteed. Meanwhile, Labour-held Barrow & Furness, the epicentre of the Labour moderate rebellion, will return its results around now. John Woodcock kicked off his re-election campaign by declaring he did not want Mr Corbyn in Numer 10. An against-the-odds victory would suggest attacking the Labour leader was a vote winner.A stunning by-election victory in Copeland in February meant the Conservatives took the seat for the firs time in more than 80 years. Can they hold on? A second victory in six months would suggest the Tories’ Cumbrian success is here to stay.

They held this now Tory seat for 23 years before 2015, so it should be winnable. Then they based their campaign on staying in the EU, but Cornwall voted Leave. The Tories will be expecting to romp home in the Conservative heartland Wiltshire seat of Devizes, while Andrew Gwynne, Labour’s election campaign chief, will find out just how effective he has been in the role when he finds out if he’s won his own Greater Manchester constituency of Denton and Reddish. Meanwhile, Jonathan Reynolds, Labour’s shadow chief economic secretary to the Treasury who is tipped as a rising star within the party, will see if he has held onto Stalybridge & Hyde. BroadlandCornwall NorthDenton & ReddishDevizesMilton Keynes SouthSt Austell & NewquayStalybridge & HydeWaveneyWiltshire North 7amTwo Labour heavyweights will have had a long wait for their results, but barring any shock voting, both Keith Vaz and Liz Kendall will win in their Leicester East and Leicester West seats. Andrea Jenkyns, who delivered the biggest shock of the last election when she ousted the shadow chancellor Ed Balls, will find out if she was able to build on her narrow 422 vote majority and keep Morley & Outwood for the Conservatives. 10pm It’s exit poll o’clock at 10pm. Key broadcasters will release details of the all-important poll, giving an early indication of how the nation voted. In the past they’ve been scarily accurate.11pmThere’s some seriously speedy vote counters up north. Safe Labour seat Houghton and Sunderland South is expected to declare its results first so all eyes will be on the north east. The constituency has beaten everyone else to it for the last five elections, announcing its result at 10.48pm in 2015. It will give us the first steer as to how Labour has done – but we can expect Bridget Phillipson to retain her strong lead. Houghton and Sunderland South Labour has huge majorities in Sunderland Central and Washington & Sunderland West so they’re pretty safe bets for Jeremy Corbyn, but it will be interesting to see what impact Prime Minister Theresa May has had here nevertheless.Sunderland CentralWashington & Sunderland West Want the best of The Telegraph direct to your email and WhatsApp?
