The nationalisation was led by Herbert Morrison, who had had the experience of uniting London's buses and underground train system into a centralised system in the 1930s. He started with the Bank of England in April 1946, whereby stockholders received compensation and the governor and deputy governor were both re-appointed. Further industries swiftly followed: civil aviation in 1946, and railways and telecommunications in 1947, along with the creation of the National Coal Board, which was responsible for supplying 90% of UK's energy needs. 1946 also saw the establishment of the National Health Service, which came into force in July 1948; railways, canals, road haulage and electricity were all also nationalised in 1948. By 1951, the iron, steel and gas industries had also been brought into public ownership.
