Too much dining and fine wine. Although allegedly, according to an ex wife, Jezza didn't do anything so utterly bourgeois as dining out, he preferred to eat cold beans straight from the tin, yum! Maybe he's eating far more beans than ever. The clue to that could be if his colleagues are sitting slightly further away,it could also be the underlying reason why Diane Abbott and Emily Thornberrry seem to wear permanently pained expressions when sitting alongside their leader on the front benches?
