John Prescott

'A former ship's steward and trade union activist, he was presented as the political link to the working class in a "New" Labour party led by modernising middle class professionals.
Prescott had overcome the handicap of failing his grammar school entrance Eleven Plus examination, to graduate from Ruskin College in Oxford.
Prescott also developed a reputation as a key conciliator in the often tense relationship between the two other senior figures in government, then chancellor Gordon Brown and former Prime Minister Tony Blair.'

He had a Hull accent too I suppose that also makes him good for a laugh!
