Ed Miliband quoted David Cameron from 2010 in support of TV election debates, but the prime minister said they should not go ahead in 2015 with only two out of three minor parties.

Mr Cameron said the the Labour leader was scared, and accused him of being "chicken" of debating with the Greens. But Mr Miliband said the Conservative leader was "frit" and running away from the debates.

The Labour, Lib Dem and UKIP leaders have asked broadcasters to press ahead with televised debates even if Mr Cameron refuses to take part.
