If the horse jokes were not bad enough, while Cameron was still at the Despatch Box, the news emerged that one of the Vice-Chairman of the Conservative Party, Mark Pritchard, has quit his role in order to be able to speak out against the government.

This stalwart of the right was a key player in the referendum rebellion last year and away from the microphones is one of the PM’s fiercest critics. Guido had a few beers with Mark Pritchard at Tory confernece back in October, he was a bit “What’s it all about Alfie?” even then.

Expect fireworks here…
