The Beveridge Report of 1942 gave the impetus for White Paper under the Conservative Health Minister Henry Willink that supported the idea of salaried GP services in health centres. The 1946 National Insurance Act under Labour Health Minister Aneurin Bevan, which laid the foundation for the NHS, reduced the clinical role of GPs in hospitals and their involvement in public health issues. The capitation fees was based on the number of patients the GP had on his list. Proposals to make GPs salaried professionals were rejected by the profession in 1948. In 1951 the capitation started to be based on the number of doctors, rather than patients.
