Former British Conservative politician Norman Tebbit has died at the age of 94. Tebbit’s son William says he died peacefully at home late Monday. No cause was given.

He held a series of roles in Margaret Thatcher’s cabinet, but left high office after his wife was seriously hurt in a bombing by the Irish Republican Army.

Thirty years later he did, as Thatcher’s secretary of state for employment. Tebbit’s 1982 Employment Act avenged the unions’ defeat of Heath. Union rights were weakened, never to be restored, and those of employers emboldened. It was a significant contribution to Thatcherism’s ledger.
