Imagine if Vikram Chandra was hosting an episode of The Big Fight and the seven politicians taking part were: Sonia Gandhi, Narendra Modi, Mulayam Singh, Mayawati, Mamata Banerjee, Jayalalitha and Uddhav Thackeray? Now imagine, this is beamed LIVE to a national audience as they debated policy, personality and ultimately the possibility of each of them getting into government. Roughly, that's what is going to unfold on live television in the UK today. The two main prime ministerial candidates - David Cameron, leader of the Conservative party and Ed Miliband, leader of the Labour party will be joined by leaders of five other smaller parties to debate with each other.
