The format agreed by the broadcasters is one debate with the leaders of the four largest parties, another with just the first, second and fourth largest parties (Tories, Labour and Lib Dems) and then a final one just before the election with just Cameron and Miliband to perpetuate the myth of two party politics.
While this is a step in the right direction, this kind of gerrymandering just isn't acceptable. Nigel Farage needs to be in all three debates, not just one.
