I suppose Farage is thinking that he is the party and the party is him, so once he's quit the leadership Ukip should die (except for the bit that makes him an MEP). He's taking his ball and going home.
It's hard to see what he's actually got against Carswell; if he's really upset by the email he's got a thinner skin than any MP should.
Has anyone told Farage he's not actually the leader any more?
UKIP is dead as a political party, but it seems that Banks and Farage have ideas to carry on with their own show. The party will split, as happened before when Kilroy Silk left to form Veritas.
It seems to me that Carswell is an awkward and divisive figure and too much of an individualist to work within a team, though I don't know what has brought this to a head just now.
If UKIP does fall apart it would be a great pity for UK politics, the Tories need some better opposition, and with a clown running the labour party, - ditto the liberals, it isn't coming from that direction.
Lets face it Carswell is a disgruntled Tory. I suspect he was accepted in and attempt to lure Tories over but it has not happened and instead disgruntled Labour voters have moved to UKIP due to Labours problems and real lack of leadership and direction.
Banks pretty much partolls it and if he feels his hard earned brass is not being used correctly then he will take it elsewhere.
Difficult to see what is in stor for UKIP, as TTT points out "Good job done, and thanks from us the leave electorate".
