Bob McCartney: next leader of the UUP?

Well stranger things have happened at sea. PA has just published an interview with a UUP source that seems to open the door to Bob McCartney rejoining the party to take the leadership. Slugger hears that although McCartney would not join the party to compete in the race, he might well consider a positive approach in the event that the party was unable to come up with a clean winner from the current set of candidates. It would certainly fit with Burnside’s warning on future co-operation with Sinn Fein. But would McCartney take the UUP anywhere it hasn’t already been?
