What a difference four days makes in the world of Ukip. This is Nigel Farage last Friday morning: “I have resigned, I have gone. I am going to take the summer off and enjoy myself for the first time in 20 years. That is what I am going to do. Building this party from scratch has been something that literally has dominated my life, seven days a week for 20 years. It has damaged my relationships with business, with family, with everything. I have not had a proper holiday since October 1993.”
