UKIP Win In UK To Result In Early General Election?

Just thinking out loud but I had the thought that Nick Clegg may be 'forced' to resign as a result of the Lib Dems disaster at the Euro and Local Council Elections. This being done behind the scenes by the Tories and Labour rather than the Lib Dems to put the wheels in motion of the coalition government failing and resulting in an early election.

I'm sure the big two who seem more or less identical these days will do anything to stop UKIP raining on their parade and an early election soon will improve their chances rather than leave it for another year and UKIP to gain even more support.

At risk of , thoughts anyone?
