More than half of Ukip’s supporters in the European elections came from disenfranchised Tory voters, a poll commissioned by Lord Ashcroft has found.
In a survery of over 4,000 people, just over half of Ukip voters said they had chosen the Tories in the 2010 general election.
Nearly 20 percent had voted Lib Dem in 2010 and 15 percent Labour.
The poll also suggests that some support for Nigel Farage may not survive into next year’s general election —51 percent of Ukip voters said they would be likely to vote for the party in 2015.
One in five Ukip voters is likely to vote Tory, and one in ten is likely to vote for Labour.
Ashcroft’s poll shows the results of 4,286 people who were interviewed online about the important issues determining who they will vote for in 2015.
Unsurprisingly 70 percent of Ukip voters said that immigration was the determining issue.
The poll follows an analysis of voting by the BBC. It showed Ukip support dropped since last year’s local elections, from 23 percent to 17 percent.
In the Ashcroft survey six in ten Ukip supporters described their vote as a protest because they were “unhappy with all established political parties at the moment”.
Ukip leader Nigel Farage wants to try and capitalise on its successes and win Ukip’s first MPs in the general election.
We have to oppose Ukip at every turn. Stand up to Ukip is a campaign drawing together anti-racists to resist Ukip where it tries to make gains.
A day of action has been called in Newark on 1 June where Ukip is standing in the local by-election.
And Stand up to Ukip has called a demonstration at the Ukip conference in Doncaster on 27 September.
Left fought good campaigns
Candidates to the left of Labour faired poorly in the elections.
Trade Unionist and Socialist Coalition (TUSC) candidates fought good campaigns, although the results were often below what they had hoped.
A lack of media coverage and the move to back Labour to stop Ukip helped squeeze the vote.
However in Southampton former Labour councillor Keith Morrell who resigned over the cuts was re-elected.
Dave Nellist won 30 percent in Coventry and Dave Gibson secured 17 percent in Barnsley.
Tottenham TUSC candidate Simon Hester told Socialist Worker,
"We stood in 8 of Tottenham's 9 wards and doubled our vote from the 2010 general election. Our highest vote of 15 percent came in Northumberland Park
“The housing crisis underpinned our best results. During the campaign large tenants' meetings enthusiastically supported TUSC candidates which contributed to the growing split within Labour ranks - many Labour Party members are deeply unhappy at the escalating attack on council housing.
"Labour consolidated its position
