The leaders of Britain's three biggest parties have gone head-to-head over the economy in the final TV debate before next week's general election.
Gordon Brown branded Conservative plans to axe child tax credits for better off families "unfair and immoral".
Tory leader David Cameron said Mr Brown had got his facts wrong and "should be ashamed of what he is doing".
Nick Clegg said Britain's tax system was "grotesquely unfair" and vowed that the Lib Dems would fix it.
Mr Brown is under pressure to salvage Labour's campaign after he had to apologise to a voter he was recorded as calling "bigoted" on Wednesday, after she questioned him about immigration.
In his opening statement, he said that "yesterday" had showed that as prime minister he did not always "get it right" but he did "know how to run the economy in good times and bad".
