He's back

Ken Livingstone is set to rejoin the Labour Party, according to a report in the Times. While the reort centres on talk of making a deal between Livingstone, the Party and Nicky Gavron (currently Labour's candidate for Mayor next year) I wonder if there's been much discussion of what happens further down the road. For instance, assuming Livingstone is re-elected next year, will he still be the candidate in 2008? If not, would the party accept him back as an MP (or even a member of the Lords!) or has he agreed to grow old gracefully? One never knows with Ken.
