The Welsh Office was a department in the Government of the United Kingdom with responsibilities for Wales. It was established in April 1965 to execute government policy in Wales, and was headed by the Secretary of State for Wales, a post which had been created in October 1964. It was disbanded on 1 July 1999 when most of its powers were transferred to the National Assembly for Wales, with some powers transferred to the Office of the Secretary of State for Wales. The Welsh Office took over the responsibilities related to housing, local government and town and country planning, etc. for Wales which had previously been the responsibilities of several other government departments. Its responsibilities included Monmouthshire, which for some purposes had earlier been considered by some to lie within England.
The post of Minister for Welsh Affairs was replaced in 1964 by the office of Secretary of State for Wales, which was given responsibility for the new Welsh Office in 1965. The Welsh Office was created to execute government policy in Wales. It took over, from other departments, functions relating to economic planning, housing, local government, sewerage, environmental health, town and country planning, Welsh national parks, historic buildings, and cultural activities. The Welsh Language Act 1967 formally dissolved the legislation which provided that references made in Parliament to England automatically included Wales, under the Wales and Berwick Act of 1746. By 1969, the role of the Welsh Office had expanded to also cover responsibilities for highway construction and maintenance, tourism, water, forestry, common land, the Historic Buildings Council for Wales, and the Countryside Commission in Wales. That year it was also given responsibility for health and welfare services, and for the use of the Welsh language in the registration of births, marriages and deaths. During the 1970s, changes in central government led to the delegation of additional functions. Most responsibilities for primary and secondary education in Wales, were transferred in 1970; and most of the child care responsibilities of the Home Office were passed to the Welsh Office in 1971. Responsibilities relating to the promotion of industry in Wales were passed to the Welsh Office in 1974-75; and in 1978 it assumed control of further education functions, and the training and supply of teachers for primary and secondary education. In 1978 it also gained sole responsibility for agriculture and fishery matters in Wales. By 1998, the Welsh Office comprised the following departments:
Agriculture
Transport Planning and Environment Group
Welsh Office Health Department
Economic Development Group
Establishments Group
Finance Group
Education Department
Health Professionals Group
Industry and Training Group
Legal Group
Local Government Group.
Most of these had headquarters in Cardiff, with offices in London to help co-ordinate policies with Whitehall departments, and to provide secretariat and support services for Ministers and the Permanent Secretary.
Establishment of the National Assembly
Following the referendum on Welsh devolution in 1997, the Welsh Office was formally disbanded on 1 July 1999 and the majority of its powers were transferred to the National Assembly for Wales. The cabinet position of Secretary of State for Wales was retained as the head of a newly formed Wales Office.
