General Election pointers
Counting is under way across the country after the ballots closed at 10pm.
The SNP is claiming 60% of votes counted so far in Falkirk. Labour had a majority in the 2010 poll.
Plaid Cymru and Labour sources say vote too close to call in Ynys Mon, where Labour had a 2,461 majority in the 2010 election.
Hywel Williams of Plaid Cymru says he is very hopeful of retaining the Arfon constituency where he had a 1,455 majority over Labour at the 2010 election.
Result in Hastings and Rye, where Tory Energy Minister Amber Rudd is defending seat, is too close to call, say Labour and Tory sources.
Labour sources say they are ahead in the count in the marginal seat of Gedling, where Labour shadow defence spokesman Vernon Coaker had a 1,859 majority over the Conservatives in the 2010 election.
Senior SNP source says it's looking good for Banff and Buchan and West Aberdeenshire and Kincardine seats. The former would be an SNP hold, with the latter a steal from the Liberal Democrats.
Conservatives are on track to retain South Ribble, party sources claim. Seema Kennedy is standing in the Lancashire constituency where David Cameron's party recorded a 5,554 majority in 2010.
SNP is ahead at Kilmarnock and Louden, party sources claim, where Labour's shadow economic secretary Cathy Jamieson is defending a 12,378 majority.
SNP sources at Paisley South count say they are very happy with samples so far. Labour described the contest between Douglas Alexander and student Mhairi Black as "close". The party is less confident about the Paisley North constituency.
Labour election agent says it is too close to call between his party and the Conservatives in Bedford. The Conservatives are defending a majority of just 1,353.
Responding to reports that Danny Alexander may be heading for defeat in Inverness, Nairn, Badenoch & Strathspey, a senior Lib Dem source said: "Too early. Very tight. Always was going to be difficult. Not heard anything more from the count."
SNP sources say that after early returns they are confident they can take Dumfriesshire, Clydesdale and Tweeddale, the Conservatives' only seat in Scotland.
