There’s space for a new party in Britain, but not for another SDP

I was 17 when the Labour party last split, in January 1981, and for a variety of reasons got quite caught up in the moment. It was partly because my father, the author of the 1945 Labour manifesto, was close to the Gang of Four — the original band of defectors — and was one of a hundred people named as supporters of the breakaway group in a full-page ad in the Guardian. But really I was just swept up by the general enthusiasm for the new party that seemed to affect vast swaths of the middle classes. If you recoiled from the economic policies of the Conservative government, which prioritised reducing inflation over full employment, but were equally querulous about the leftward shift of the Labour party, the SDP was an appealing alternative.

I never went as far as becoming a member — I wasn’t a joiner in those days — but was enough of a supporter to join my father on a trip to Warrington in Lancashire to campaign for Roy Jenkins in a by–election about six months later.
