# Peter Kerr, 12th Marquess of Lothian

Peter Francis Walter Kerr, 12th Marquess of Lothian, KCVO (8 September 1922 – 11 October 2004) was a British peer, politician and landowner. He was the son of Captain Andrew William Kerr by his wife, Marie Kerr. Both of his parents were male-line descendants of William Kerr, 5th Marquess of Lothian.

## Life and career

His father, Andrew Kerr, and grandfather, Lord Walter Kerr, the son of the 7th Marquess of Lothian, were officers in the Royal Navy. He was educated at Ampleforth College and Christ Church, Oxford, and joined the Scots Guards. He succeeded his cousin, Philip Kerr, 11th Marquess of Lothian, in 1940, and married a distant cousin, Antonella Newland (d. 2007), daughter of Major General Sir Foster Newland, on 30 April 1943. Lord and Lady Lothian had six children: two sons and four daughters. His wife pursued her own career as a journalist, and founded the Women of the Year Lunch. The family were mainly based at their estates in the Borders, at Newbattle Abbey and Monteviot. The 11th Marquess had left Blickling Hall in Norfolk to the National Trust. Another family house at Melbourne Hall in Derbyshire was opened to the paying public in 1952.
Lothian took part in the Wolfenden inquiry into the UK's laws on homosexuality and prostitution from 1954. He joined the UK's delegation to the United Nations General Assembly during the Suez crisis in 1956, and was later sent as a delegate to the Council of Europe in 1959 and the Western European Union. He served as parliamentary private secretary to the foreign secretary, Lord Home, from 1960, and was also a whip in the House of Lords. He served as a junior minister at the Ministry of Health during the short period of Lord Home's term as prime minister in 1964. He returned to the Foreign Office with Alec Douglas-Home (then formerly Lord Home) in 1970, serving as parliamentary under-secretary for two years. He was nominated as a member of the European Parliament in 1973, when the UK joined the European Economic Community.
Lord Lothian retired from politics in 1977, after which he served as Lord Warden of the Stannaries, Keeper of the Privy Purse to the Duke of Cornwall, and Chairman of the Prince's Council for the Duchy of Cornwall. He was appointed KCVO in 1983. He was also a member of the Royal Company of Archers, commandant of the Special Constabulary in the Scottish Borders, and a Knight of Malta.
He returned the Franciscan monastery of San Damiano, near Assisi, to the Franciscan Friars Minor in 1979, and he ceded control of Monteviot and Melbourne House to his elder and younger son, respectively, in the 1980s, to take on the restoration of Ferniehirst Castle in Roxburghshire.
