Early career

He entered the diplomatic service in 1930, serving at the Foreign Office in London as well as at the embassy in Berlin.

He became Conservative Party Member of Parliament (MP) for Norwood in south London in a by-election in March 1935, at which he was opposed by an Independent Conservative candidate sponsored by Randolph Churchill.

In May 1935, he was in effect saying that Germany should have a predominant place in central Europe, so that Britain could be free to pursue her colonial interests without rival.^[5]

The Duncan Sandys case

In 1937, Sandys was commissioned into the 51st (London) Anti-Aircraft Brigade, Royal Artillery, of the Territorial Army (TA).^[6] In 1938, he asked questions in the House of Commons on matters of diplomatic service in 1930, serving at the Foreign Office in London as well as at the embassy in Berlin.

In 1937, Sandys was commissioned into the 51st (London) Anti-Aircraft Brigade, Royal Artillery, of the Territorial Army (TA).^[6] In 1938, he asked questions in the House of Commons on matters of national security that reflected his TA experience. He was subsequently approached by two unidentified men, presumably representing the secret services, and threatened with prosecution under section 6 of the Official Secrets Act 1920. Sandys reported the matter to the Committee of Privileges which held that the disclosures of Parliament were not subject to the legislation, though an MP could be disciplined by the House.^[7][8] The Official Secrets Act 1939 was enacted in reaction to this incident.^[9]

Wartime career

During the Second World War he fought with 51st (London) HAA Regiment in the Norwegian campaign and was wounded in action; this left him with a permanent limp.^[8]

His father-in-law gave him his first ministerial post as Financial Secretary to the War Office from 1941 to 1944 during the wartime coalition government. From 1944 to 1945 he served as Financial Secretary to the War Office from 1941 to 1944 during the wartime coalition government. From 1944 to 1945 he served as Minister of Works for the remainder of the coalition and in the Churchill Caretaker Ministry. While a Minister he was also chairman of a War Cabinet Committee for defence against German flying bombs and rockets, where he frequently clashed with the scientist and intelligence expert R. V. Jones.^[10] However, he lost his seat in the 1945 general election. He resigned his TA commission as a lieutenant-colonel the following year.^[8]

Sandys was responsible for establishing the European Movement in Britain in 1947 and served as a member of the European Consultative Assembly from 1950 until 1951. He was elected to parliament once again at the 1950 general election for Streatham and, when the Conservatives regained power in 1951, he was appointed Minister of Supply. For most of his time in that role, his private secretary was Jack Charles. As Minister of Housing from 1954, he introduced the Clean Air Act and in 1955 introduced the green belts.

He was appointed Minister of Defence in 1957 and quickly produced the 1957 Defence White Paper that proposed a radical shift in the Minister of Defence in 1957 and quickly produced the 1957 Defence White Paper that proposed a radical shift in the Royal Air Force by ending the use of fighter aircraft in favour of missile technology. Though later ministers reversed the policy, the lost orders and cuts in research were responsible for several British aircraft manufacturers going out of business. As Minister of Defence he saw the rationalisation (i.e., merger) of much of the British military aircraft and engine industry.

Sandys continued as a minister at the Commonwealth Relations Office, later combining it with the Colonies Office, until the Conservative government lost power in 1964. In this role he was responsible for granting several colonies their independence and was involved in managing the British response to several conflicts involving the armed forces of the newly independent countries of East Africa.^[11]

He remained in the shadow cabinet until 1966 when he was sacked by Edward Heath. He had strongly supported Ian Smith in the dispute over Rhodesia's Unilateral Declaration of Independence. He was not offered a post when the Conservatives won the 1970 general election, but instead served as leader of the United Kingdom delegation to the Council of Europe and Western European Union until 1972 when he announced his retirement. The next year he was made a Companion of Honour.

In 1974 he retired from parliament and was awarded a life peerage on 2 May. As the title of Baron Sandys was already held by another family, he followed the example of George Brown and incorporated his first name in the title Baron Duncan-Sandys of the City of Westminster.^[12] He was an active early member of the Conservative Monday Club.

In 1935, Duncan Sandys married Diana Churchill, daughter of the future prime minister Winston Churchill. They divorced in 1960.

In 1962, he married Marie-Claire (née Schmitt), who had been previously married to Robert Hudson, 2nd Viscount Hudson.^{Robert Hudson, 2nd Viscount Hudson.^{[citation needed]} The marriage lasted until Sandys' death.}

It has long been speculated that he may have been the 'headless man' whose identity was concealed during the (then considered) scandalous divorce trial of Margaret, Duchess of Argyll, in 1963.^[13]

Sandys died on 26 November 1987 at his home in London.^[14] He is buried in the churchyard of St Nicholas in Child Okeford, Dorset. His grave is marked by a horizontal white slab.^[15]

From his first marriage, with Diana Churchill:

• The Hon. Julian Sandys (19 September 1936 – 15 August 1997)
• The Hon. Edwina Sandys (born 22 December 1938)
• The Hon. Celia Sandys (born 18 May 1943). She married firstly Michael Kennedy and secondly Laura Sandys (born 5 June 1964). She was a Conservative Member of Parliament for South Thanet. She is often incorrectly referred to as being related to Winston Churchill.

Between 1969–1984 he was President of Europa Nostra and acted for the preservation of the European cultural and architectural heritage.

His business activities included a Directorship of the Ashanti Goldfields Corporation, which was later part of Lonrho of which he became chairman. He was therefore caught up in the scandal in which Lonrho was revealed to have bribed several African countries and broken international sanctions against Europa Nostra and acted for the preservation of the European cultural and architectural heritage.
