The UK Independence Party has overtaken the LibDems for the first time ever, according to a new poll.
In a YouGov poll conducted for The Sun, the anti-EU party has increased its support to 9%, while the Liberal Democrats have slipped to 8%.
The poll, ahead of May's local elections, also puts Labour 11 points ahead of the Tories. Another poll by Populus, out today, shows Labour are on a nine point lead over the Conservatives.
The UK Independence Party has previously trailed the LibDems, rising only once to level pegging with Nick Clegg's party.
The news comes as another YouGov poll suggested only seven of 57 LibDems would survive as MPs in a general election, with LibDem leader Nick Clegg and business secretary Vince Cable among those in danger.
