Clement Attlee's proved one of the most radical British governments of the 20th century, enacting Keynesian economic policies, presiding over a policy of nationalising major industries and utilities including the Bank of England, coal mining, the steel industry, electricity, gas, and inland transport (including railways, road haulage and canals). It developed and implemented the "cradle to grave" welfare state conceived by the economist William Beveridge. To this day, the party considers the 1948 creation of Britain's publicly funded National Health Service (NHS) under health minister Aneurin Bevan its proudest achievement. Attlee's government also began the process of dismantling the British Empire when it granted independence to India and Pakistan in 1947, followed by Burma (Myanmar) and Ceylon (Sri Lanka) the following year. At a secret meeting in January 1947, Attlee and six cabinet ministers, including Foreign Secretary Ernest Bevin, decided to proceed with the development of Britain's nuclear weapons programme, in opposition to the pacifist and anti-nuclear stances of a large element inside the Labour Party.
