Liberal backbench MP Andrew Laming has failed in his attempt to have Hansard change the accusation of corruption he shouted at Prime Minister Julia Gillard.
Yesterday during question time Dr Laming was heard to shout "You are corrupt!" as the Prime Minister answered an Opposition question about her dealings as a lawyer representing the AWU and a union "slush fund" she set up.
The Prime Minister maintains that she had no idea of the purpose of the fund and denies all wrong-doing in relation to the matter.
Dr Laming's interjection was recorded in Hansard, and in the notes of journalists, but this morning he backtracked, claiming he simply shouted "corrupt" during the furore, and others, including the Hansard editor who sits in the chamber, must have misheard him.
Dr Laming said other people were shouting the word at the same time.
He said one Coalition MP had told him he used the word at the same time, but declined to identify the member.
''I think that was why it was so audible,'' he said.
But the Hansard office says it is doing a final review of the audio but it is unlikely to be changed, despite Dr Laming's request his interjection be expunged.
Dr Laming requested the change today but after reviewing the audio of yesterday question time, Hansard officials kept the "You are corrupt!" interjection as originally recorded.
Dr Laming said: "We will accept the Hansard determination."
On Wednesday when he made the statement, Dr Laming was forced to withdraw the comment and ejected from the chamber.
Today Dr Laming tweeted that he felt ''vindicated'' by a Fairfax online poll which showed 75 per cent of respondents felt Ms Gillard had not satisfactorily explained her involvement in the scandal.
