Apart from everything else Blair has done to make us unhappy with him he is also Bush's closest ally. People can use this opportunity to give him a hard kick and wake up call and hopefully the publics combined strength and voting power over here might even weaken Blair enough that he has to adopt a hung government that certainly wouldn't stand for supporting Bush's wars or maybe even remove him from office completely.
Here's hoping.
