TV election debates: broadcasters call David Cameron's bluff

Broadcasters and Downing street were at loggerheads on friday after the television companies have made it very clear that they would only press head with the only plans to hold three seperate election to stop chaos from taking place. The network said that they would go ahead and allow the three debates during the election campaign- two of them taking place between the seven party leaders and one proposed between head to head the prime minister and Ed Miliband.
I think this whole idea of having only three debates taking place is a smart idea so there wouldnt be confusion and chaos created as a lot people think that there should be more than one debate taking place when it comes down to the election until the thursday in which the election actually takes place.
