Lord Walker: Durable left-of-centre Conservative politician who served

Peter Walker was one of the great survivors of the Conservative Party, spanning the Heath and Thatcher eras. At the time of his voluntary retirement in 1990, a few months before Thatcher's downfall, no 20th century politician, apart from Churchill and Lloyd George, had served longer in Cabinets and Shadow Cabinets, and it was appropriate that he should call his memoirs Staying Power. Though he never held one of the "great" offices of state, the variety of posts that he did fill, and the timing of them, ensured that he made significant contributions to British public life, proving a minister of considerable executive efficiency. Political durability was not his only claim to fame. His earlier role as a successful city financier, particularly with Jim Slater, would alone have ensured him the attention of serious commentators.
