But Diary can exclusively reveal that Cameron's PR credentials go back a little further than that.
While ensconced with the great, good and largely wealthy denizens of Brasenose College, Oxford, the leader of the opposition joined many a bawdy social club. One of those clubs, the Octagon, was a posse of Brasenose's finest sportsmen who were dedicated to finding the finest eateries in Oxford.
Look closely at the Octagon minutes and you will find the name David Hargreaves, MD of PR agency Bite, and a rather fine cricketer.
Hargreaves confirmed that the other David was 'great fun to drink with' and that being a member of a collective devoted to eating definitely aided the transition to a career in PR.
