John Prescott opted for the BBC Radio 4 Today Programme to plug his BBC2 documentary on the British class system - plenty of targets there for Prescott's tirade against the posh. Defending his grammar school credentials, Today presenter Evan Davis attempted the obligatory Mandelson/yacht probe but Prescott was having none of it. "Of all the big issues, you want to know what Prescott says about Mandelson and blah blah - you're so damn predictable," Prezza railed - just after seven minutes into this audio clip. "If it's glass half full or half empty you'll always get the half empty one. I listen to your programme and Evan - you're always predicting the misery of the end of the world, that Gordon Brown is going down. You're a programme of depression. Why don't you just get on your yacht and get going." And with that, the former deputy PM flounced out of broadcasting House and ... into his Jag, presumably.
