Ken Livingstone has repeated claims that he did not scuffle with his partner or throw a man 15 feet over a wall during a late night party.

He said that voters could no longer believe anything "about my policies or my private life" published in London's Evening Standard.

The mayor said the assault claims were "outright lies" published for political reasons.

Calling for the editor of the newspaper to be dismissed, he rejected claims that he fled the scene of the party after assaulting a man and manhandling his pregnant girlfriend.

His intervention came as members of the Greater London Assembly sought clarification over claims that he gave a misleading account of his involvement in the alleged assault and misused his staff in rebutting the allegations.

Livingstone said he would stick by the statement he gave in the assembly last week.

"The statement I made last week has not changed - I have not altered one sub-clause. I will not be changing what I said to you last week, or this week," he said.

Livingstone told assembly members he would happily take a lie detector test to prove he was telling the truth.

Rejecting allegations given front page coverage in the Evening Standard, the mayor went for full disclosure.

Livingstone claimed he had just three glasses of sauvignon blanc before going to sleep at a party in North London.

He said he was "tired, as I often am at parties".

He then admitted that at 1.00am, after having slept for three hours, he left the party after a "row" with his girlfriend.

Livingstone denied that he had "manhandled" Beale after being incorrectly told she had been smoking.

He claimed that Robin Hedges, 35, had then been told that the row with Beale had "turned nasty" when, in fact, it had been settled amicably.

The mayor says the man left the party to confront him, whereupon he was knocked to the ground.

Livingstone admitted that he did become involved in a scuffle with Hedges after being "jumped" upon.

"I did not assault Emma and I did not push Robin over the wall either," he said.

Livingstone claims that Hedges fell over a wall into a stairwell after what he described as "an accident" after walking back up the steps into the North London flat.

"This is exactly the sort of thing that can happen to anybody," he told the assembly. "There had been an accident - he had fallen over."

Whilst Hedges has said he will not press charges, he is standing by the assault claims.

He says the mayor lost control, before pushing him over the wall.

Hedges was taken from the scene by ambulance and has subsequently needed a brain scan.

GLA members demanded a further explanation from the mayor - calling for an investigation by either the police, the Press Complaints Commission (PCC) or the local government standards board.

Eric Ollerenshaw, the GLA's Tory leader, said "this issue is no longer about the mayor's private life, instead it is about the trust and credibility of the mayor".

Livingstone said he did not want to drag out the affair by suing the Evening Standard or through a formal complaint to the PCC.

"I am happy for seven million Londoners to read it for themselves - that's the biggest jury you can find," he said.

The hour-long emergency meeting of the GLA ended after members decided to take no further action against the mayor.
