UK Election results 2015: Timeline for results of the key seats to watch
When will my constituency declare? When will live coverage start? What are the key seats to watch, and when will we get the results?
Polling stations will close in the UK's 650 constituencies, and ballot boxes will be transferred to their count venues. An exit poll will offer a guess about the share of the vote for each party and how many seats they have. But actual results will take much longer.
Houghton & Sunderland South –traditionally the first seat to declare. Safe Labour territory
Nuneaton - one of the first seats on the Labour target list to declare. If Labour don't win this from the Tories, Ed Miliband is in for a bad night.
Battersea, currently held by the Tories, is a top Labour target in London.
East Kilbride, Strathaven & Lesmahagow, Glenrothes, Kirkaldy & Cowdenbeath and Lanark & Hamilton East. SNP gains here will confirm that a sea-change is underway in Scotland.
Thornbury and Yate - held by the Lib Dems in 2010: can the Conservatives obliterate their coalition partners in the south-west of England? Gains from the Lib Dems are key to Tory hopes.
City of Chester: a Conservative vs Labour contest. A Labour gain would suggest the party is having a good night.
Westminster North – another Conservative-held Labour target in London.
Bedford: Tory-held in 2010, this is another key battle between Conservative and Labour.
Bolton West – this was a top Tory target in 2010, but Labour held on. A Conservative gain here would suggest the party is on course for a great night.
Carlisle – Conservatives have thrown resources into defending one of their rare northern seats from Labour.
Croydon Central: Big, big test of Tory resilience in London. Can the Conservatives hold here in face of strong challenge from Labour and loss of votes to Ukip?
Hampstead and Kilburn – Tories came within an inch of a surprise win here in 2010. A win here this time would be an even bigger surprise.
Thurrock – Ukip’s best hope? Tim Aker hopes to be the party’s first MP elected at a general election.
Gedling – another Tory target in 2010, but probably safe Labour this time. But a Tory win here would terrify Labour.
Kingston & Surbiton – can Ed Davey, a Lib Dem Cabinet minister keep his seat?
Enfield North - Conservative-held marginal: a Labour gain would hurt David Cameron badly.
Blackpool North and Cleveleys - Conservative-held marginal: a Labour gain would hurt David Cameron badly.
Loughborough – Nicky Morgan, Tory education secretary, is defending a marginal seat here.
Weaver Vale – Tory-held marginal in the north-west; key test of Tory fortunes in the region with the most marginal seats.
Broxtowe - Conservative-held marginal: a Labour gain would hurt David Cameron badly.
Doncaster North – Ed Miliband’s victory speech will give clues about Labour morale and strategy.
Sheffield Hallam: Will Nick Clegg survive?
Nick Clegg is defending his Sheffield Hallam seat from Labour
Clacton – Douglas Carswell is seeking to keep this seat for Ukip, and most Tories expect him to win. A Conservative gain here would delight and surprise Tories.
Witney - David Cameron's victory speech here will show us how the Conservatives will approach the overall results: will he claim victory even if he doesn't have a majority, or hint at another deal with the Lib Dems?
Inverness – Danny Alexander, another senior Lib Dem, is fighting for his life against the SNP.
Brentford & Isleworth – another key Tory marginal in London.
Hove, Brighton & Kempton, Wirral West and Warrington South – all marginals held by the Tories in 2010: losses to Labour here will be major setbacks to the Conservatives.
Finchley and Golders Green – a Labour gain from the Conservatives in Margaret Thatcher’s old seat would be unlikely but dramatic.
Rochester and Strood – Mark Reckless is defending this seat for Ukip, a key test of the Tories’ ability to win back Ukippers.
Thanet South – Nigel Farage either becomes an MP or has to resign as Ukip leader.
Ukip leader Nigel Farage has said he will step down if he does not win in Thanet
Uxbridge and Ruislip South – Boris Johnson will win, but will he be celebrating a Tory return to government?
Noon on Friday
Warwick & Leamington – another crucial Conservative vs Labour marginal. If the overall numbers are very close, we could be waiting for the result here to tell us who can govern.
St Ives - due to be the last constituency to declare. Will the general election hang on the result here, where the Lib Dems are trying to hang on to a seat they've held since 1997?
