 Benn "was stridently against membership", and campaigned in favour of a referendum on the UK's membership.The Shadow Cabinet voted to support a referendum on 29 March 1972, and as a result Roy Jenkins resigned as Deputy Leader of the Labour Party.In the Labour Government of 1974, Benn was Secretary of State for Industry and as such increased nationalised industry pay, provided better terms and conditions for workers such as the Health and Safety at Work Act 1974 and was involved in setting up worker cooperatives in firms which were struggling, the best known being at Meriden, outside Coventry, producing Triumph Motorcycles.
