would have happened whichever political party was in power, no matter who was Prime Minister.
The reaction to it may have been different, but that's something that can't possibly be tested. David Cameron will obviously blame the current problems on Gordon Brown - it's his job to do so.
Would the recession have been avoidable? I doubt it - there was a dynamic at work which originated beyond our shores, and although it might be argued that we should have seen the warning signs far sooner, that is also something that sounds good with the benefit of hindsight. The truth is, some people did foresee trouble, but they were largely ignored - everyone was far too busy lending and borrowing.
All that is largely meaningless now. What we must concentrate on is not what got us into this situation, but what we must do to get out of it.
