Join again, Livingstone

So, it seems that Tony Blair does have a reverse gear, at least on his opinions about Ken Livingstone.

One thought that did strike me regarding Ken's return, though, was the question of what it means in terms of the supposed ongoing struggles within the Labour Party. Given that Livingstone has been quite a strong critic of Gordon Brown over the years, might Blair think that having him back in the party could be a good thing for him in terms of the party's own battles? I'm sure Spin and others can shoot this theory down, but it seems to me that, especially with Blair's 'hey Ken, you're a great bloke, let's be friends' mea culpa today, that Tony may see Livingstone as a potential asset in any battles he may have with Gordon this year.
