“Desperate” was the first text I received, from a Shadow Cabinet member, on the news of Nigel Farage’s resignation and his subsequent by-election announcement. It is a fairly accurate portrayal of the state of affairs. Realising he is up to his neck in controversy, Farage is attempting to jump the gun – to fight a by-election on his own terms before he is found guilty of misconduct. “Cowardly,” another MP tells me. “He’s jumped before being pushed.” I couldn’t think of a more accurate description.
