There seems to be some ground to the thinking that after the next election there will be a coalition between the Torys and the Lib Dems... That being said it may simply be a gambit made by Nick Clegg as the only way in which his party will get anything near national government.
Firstly, the party aproves tax cuts for the manifesto.
Secondly, as Paul Waugh points out, the mood of the LD's as well as Clegg seems to be based around de-throneing Labour. Coupling this with their base expansionist ideals a coalition seems benificial.
So. There you have it... Im sure there is more, but I am at work and probably shouldnt even be blogging at all.
