UKIP's only MP is a full throttle anarcho-capitalist who opposes any immigration control whatever.
The party's only purpose is withdrawal from the EU, which is either about to happen, or about to be ruled out permanently.
Either way, that is the end of UKIP, which is itself the anchor of any Right beyond Cameron.
He will be the Right of British politics, with Corbyn as the Left. The twin poles will be Blairism and Bennism.
And that will be that.
