Crikey despite their cuddly beard ‘n’ sandals image, these Lib Dems can be vicious. Bringing on a strange attack of deja vu they’ve had a mini night of long knives again and duly knifed their leader Sir Ming Campbell, plunging them into a leadership contest – the second one in as many years.

I remember thinking after the Ealing Southall by-election, that the result was good news all round: Gordon Brown victorious, Cameron fatally bruised and Ming firmly in post. What a difference a couple of months can make.
