Key points from the UK General Election counts
Here are 10 key points from the election counts.
:: Exit poll puts the Conservatives ahead on 316 seats, with Labour on 239, the Liberal Democrats on 10, the SNP on 58 and Ukip on 2.
:: Houghton and Sunderland South is the first seat to declare. The result is announced at 10.48pm, four minutes quicker than in 2010. Labour's Bridget Phillipson holds the seat with 21,218, up 4.7% on her 2010 figure.
:: Swindon North - the fourth count to declare - gives Conservatives their first success of the night as Justin Tomlinson holds his seat with 26,295 votes, up 5.8% on his 2010 tally.
:: The first big name of the night to keep her seat is International Development Secretary Justine Greening who holds Putney for the Conservatives.
:: SNP take Kilmarnock & Loudoun from Labour and Co-operative, the first in a cascade of SNP gains which included Labour's safest seat in Scotland, the Kirkcaldy and Cowdenbeath constituency previously held by former prime minister Gordon Brown which saw a 34.55% swing from Labour to the SNP. Former first minister Alex Salmond wins the Gordon seat.
:: Labour shadow foreign secretary Douglas Alexander becomes the first big scalp of the night, losing his Paisley and Renfrewshire South seat to the SNP's Mhairi Black. He is quickly followed by Scottish Labour leader Jim Murphy who loses his East Renfrewshire seat to the SNP's Kirsten Oswald.
:: Conservatives hold Labour's number one target seat, Warwickshire North. Craig Tracey wins 20,046 votes compared to Mike O'Brien, for Labour, on 17,069.
:: A disastrous night for the Liberal Democrats saw Business Secretary Vince Cable lose his Twickenham seat to the Conservatives while Energy Secretary Ed Davey lost Kingston and Surbiton to Conservative James Berry. Lynne Featherstone is defeated by Labour in Hornsey & Wood Green. Simon Hughes loses the Bermondsey and Old Southwark seat he had held his seat for 32 years to Labour.
:: Ukip wins its first ever seat in a general election, although former Conservative MP Douglas Carswell sees a much reduced majority - down from 12,404 to 3,437 - compared to last year's by-election. The party is forced into third place in Thurrock, one of its highest priority seats, as Jackie Doyle Price won re-election for the Conservatives by a slender majority over Labour.
:: Boris Johnson returns to Parliament as MP for Uxbridge and South Ruislip, winning a majority of more than 10,000 votes. He previously served as MP for Henley for seven years before leaving to take up the City Hall reins in 2008.
