Is Clegg about to do a left turn?

Nick Clegg is the subject of The Independent’ s ‘You ask the question..’ feature today. His answer to this question is particularly interesting:

Clegg: Blair was more wrong, Brown’s more incompetent. Now, I may be reading way too much into a pithy response but it rather suggests to me that Clegg is shifting his political positioning leftwards. It might be that this is in response to the stories about him becoming Home Secretary in a Tory government or he might have decided that given the current political environment, the Lib Dem’s best chance of gains at the next election are in Labour seats.
