The Prime Minister said he would support the continuation of televised general election debates between the party leaders, introduced in 2010 for the first time.
He said: "On TV debates, I'm in favour of them, I think they are good and I think we should go on having them, and I will play my part in trying to make that happen."
Mr Cameron has previously indicated that he might want changes in the precise format for the debates. Today he said he did not feel that they had affected the result in 2010.
He said: "I think actually from memory the polls going into the start of the last election were pretty similar to the polls coming out of the last election, so I suspect the result would have been pretty much the same anyway."
