My grandfather, a bit like John Prescott, was a pitbull terrier of a man who dedicated much of his life to the Labour Party in Hull. Like Prescott, he always considered himself working class; unlike him, he never got to drive even one Jag. My father, being a rebel, joined the expanding middle classes, moving south in the 1950s and qualifying as an architect. He never had much time for the Labour Party. The goal of spreading such opportunities will dominate the forthcoming white paper on fairness, and underlies this week’s report from the prime minister’s strategy unit.
