An influential Conservative figure has blamed Prime Minister David Cameron for Tory’s failure to open up an opinion poll lead over Labour party.
Lord Ashcroft said that some people who prefer Mr Cameron to Mr Miliband are deciding to vote Labour, as the Labour leader performs better than voters and the Tories expected.
The comments of the former Tory deputy chairman, who is now a pollster come as the Tories’ hopes of a breakthrough are dashed by the latest “poll of polls” for The Independent.

According to the poll, the two biggest parties remain deadlocked. They are both on 33 per cent, with Ukip on 14 per cent, the Liberal Democrats on 8 per cent and the Greens on 5 per cent.
As the electoral map favours Labour, such a result would give the party 293 seats to the Tories’ 270, putting Miliband in pole position to become prime minister in a hung parliament.
UK general elections are set to be held on May 7.
