Opposition leader David Cameron has told the prime minister that the Labour Party was "too incompetent" to remove him after last week's failed putsch.
During heated question time exchanges on 13 January 2010,
Mr Cameron said the past week had shown
that Mr Brown's cabinet and his party were "too disloyal to support him".
But Gordon Brown mocked the Tory leader over his "airbrushed" poster campaign and attacked his plans for tackling the recession as the "policies of the 1980s".
He said the Tory leader "looks very different" to his picture on the billboards around the country.
"If you can't get your photograph right, it's pretty difficult to get your policies right as well," he said.
Mr Cameron then asked Labour MPs which of them planned to use the prime minister's pictures on their election material.
As a handful of MPs put their hands up, Mr Cameron said: "There are six of them who don't want him in the cabinet and just four who are going to put his picture on it.
"He has been airbrushed out of the whole campaign," he quipped.
Mr Brown also faced calls from the Lib Dems to voluntarily bring forward his appearance at the Iraq Inquiry to before the General Election.
Nick Clegg said people were "entitled" to know Mr Brown's role
in the decision to go to war before voting as he "signed the cheques".
But the PM said he was acting on the recommendation of the Chilcot inquiry on when he should appear.
As prime minister's questions finished,
Speaker John Bercow announced that the Commons would hold an emergency debate
on Thursday after the Liberal Democrat MP for Birmingham Yardley, John Hemming, claimed he had been "intimidated" by a firm of solicitors.
Mr Hemming believed he had received an email amounting to a "contempt of the House", Mr Bercow told the Commons.
