Minister for Co-ordination of Defence (1936–1940) The position of
minister for co-ordination of defence was a
British Cabinet-level position established in 1936 to oversee and co-ordinate the rearmament of Britain's defences. It was established by the prime minister,
Stanley Baldwin, in response to criticism that Britain's armed forces were understrength compared to those of
Nazi Germany. When the
Second World War broke out, the new prime minister
Neville Chamberlain formed a small
War Cabinet and it was expected that the minister would serve as a spokesperson for the three service ministers, the
secretary of state for war, the
first lord of the admiralty and the
secretary of state for air; however, political considerations resulted in all three posts being included in the Cabinet, and this role proved increasingly redundant. In April 1940 the position was formally wound up and the functions transferred to other ministers.
Minister of Defence (1940–1964) The post of
minister of defence was responsible for co-ordination of defence and security from its creation in 1940 until its abolition in 1964. The post was a
Cabinet level post and generally ranked above the three service ministers, some of whom, however, continued to also serve in Cabinet. On his appointment as prime minister in May 1940,
Winston Churchill created for himself the new post of minister of defence. The post was created in response to previous criticism that there had been no clear single minister in charge of the prosecution of
World War II. In 1946, the post became the only cabinet-level post representing the military, with the three service ministers – the
secretary of state for war, the
first lord of the admiralty, and the
secretary of state for air, now formally subordinated to the minister of defence.
Secretary of State for Defence (1964–present) The post was created in 1964 as successor to the posts of minister for coordination of defence and minister of defence. It replaced the positions of
first lord of the admiralty,
secretary of state for war and
secretary of state for air, as the
Admiralty,
War Office and
Air Ministry were merged into the
Ministry of Defence (the secretary of state for war had already ceased to be a cabinet position in 1946, with the creation of the cabinet-level
minister of defence). In 1964 the position was incorporated as a
corporation sole. } == Timeline ==
