The UK Independence Party leadership must be cursing the day they welcomed Robert Kilroy-Silk in with open arms as the star of their election campaign. As the row over the party leadership runs on, they must be thinking how much better off they might have been without him.
He is now the cuckoo in the UKIP nest. There are two possible ends to this situation. One is that he will get rid of the other chicks to take over the party and turn it into one along the lines of the familiar continental European populist right-wing model. The other is that they will force him out, leaving him to plough a lonely furrough as an independent while they muddle along much as they were before his arrival.
