Broadcasters have responded by taking a firm stance with the prime minister and his communications team; sticking with their plan of three debates - two with the leaders of seven parties and one with just Cameron and Labour leader Ed Miliband.
Miliband has seized on the prime minister's apparent unwillingness to agree to the debates, branding him a "chicken" (yes, it really is that high-brow).
Luckily, the PM has people like Tory MP Jacob Rees-Mogg to defend him from such name-calling.
Rees-Mogg appeared on Channel 4 News last night where he laid bare the real reason for Cameron's predicament - a left-wing conspiracy. Really.
David Cameron said that he would participate in a debate at an earlier stage so that it didn't take over the whole of the election campaign and the broadcasters arrogantly rejected his offer.
Rees-Mogg went on to say:
You have to ask the broadcasters what their motive is, there are a lot of left-wing people in the broadcasters… the BBC is well known for its left-wing views and it seems to want to have sets of debates that support left-wing parties
