Nick Clegg is set to lose his seat, according to the latest Lord Ashcroft poll of his Sheffield Hallam constituency.
The Liberal Democrat leader is trailing behind Labour candidate Oliver Coppard by one point, but has narrowed the gap from the pollster's survey of the seat last month.
Mr Clegg won the seat with a massive majority of more than 15,000 seats in 2010 and he insists his own party's private polling shows him "firmly ahead".
He also pointed to the fact that Lord Ashcroft does not include the names of the candidates in his polling and said voters are much more likely to support Mr Clegg when they see his name on the ballot paper.
The poll shows Mr Coppard leading on 37 per cent, Mr Clegg trailing one point behind on 36 per cent, with the Conservative candidate Ian Walker on 15 per cent.
Mr Walker's support has fallen from Lord Ashcroft's poll of Sheffield Hallam last month at the same time as Mr Clegg's support has edged up slightly, suggesting Tory supporters are lending their vote to the Liberal Democrat leader to block Labour from winning.
Talking to reporters on the campaign trail, Mr Clegg said: "Just call me old-fashioned, but if you are going to try to work out how people are going to vote, ask them the question they are actually going to be asked on polling day."
