WEASEL Lib Dem chief Nick Clegg yesterday pledged to stop voters having a say on the re-jigged EU Constitution.

Squirming Clegg was pressed FIVE times in an interview over whether his MPs would bale out Gordon Brown if a referendum looked likely.

He finally admitted he WOULD order his party to come to the PM’s rescue in a Commons vote.

Labour rebels will put down an amendment in the coming weeks hoping to force a referendum.

Asked if the Lib Dems would abstain if they held the balance, Clegg answered: “I certainly hope not. No.”

The calculating new Lib Dem leader then added he would see what the “parliamentary mathematics” were before deciding his position.

Last night Clegg — who backed calls for a poll at the 2005 General Election — was blasted for failing his first big test as leader during the grilling on BBC Radio 4’s Today programme.

Party insiders were furious that he had changed tack after it was agreed that the policy was to abstain from all votes on a poll.

Shadow Foreign Secretary William Hague said: “They told voters they wanted a referendum. Then they decided to abstain from a referendum.

“Now they will bale out a failing and discredited Government which is itself breaking its election promise.

“To change their votes according to the parliamentary arithmetic is exactly what discredits British politics — acting without principles at all.”

UK Independence Party leader Nigel Farage called Lib Dems’ behaviour “thoroughly dishonest”.

Clegg’s party claims the EU Treaty is different from the dumped Constitution.

The Bill to ratify the Treaty — signed by Mr Brown last month — cleared its first Commons hurdle on Monday.
