Malcolm Sinclair, 20th Earl of Caithness

Malcolm Ian Sinclair, 20th Earl of Caithness, (born 3 November 1948), is a Scottish Conservative politician, hereditary peer and former member of the House of Lords. He is also 20th Lord Berriedale, 15th Baronet, of Canisbay, Co. Caithness, and chief of Clan Sinclair. He is the Chief Executive of the Clan Sinclair Trust.

Early life and education Sinclair was born in 1948, the only son of Roderick Sinclair, 19th Earl of Caithness and his second wife Madeline Gabrielle Ormerod (née de Pury). Sinclair's mother was possibly descended from the de Pury family of Neuchâtel, Switzerland, who were members of the Prussian nobility.

He was educated at Blairmore School, Aberdeenshire, at Marlborough College and at the Royal Agricultural College (now Royal Agricultural University), Cirencester.

Sinclair succeeded to the earldom of Caithness and its subsidiary titles upon the death of his father in 1965.

House of Lords and political offices Lord Caithness served as a House of Lords government-whip under Margaret Thatcher from 1984 to 1985. He then moved to the Department of Transport as a Parliamentary Under Secretary of State, serving until 1986, the year when he became Minister of State at the Home Office. In 1988, he was once appointed Minister of State at the Department of Environment. In 1989, he became Paymaster General and a Minister of State in the Treasury.

In 1990, Caithness was appointed Minister of State at the Foreign Office, and then, in 1992, back to the Department of Transport. He was made a privy counsellor in 1990.

With the passage of the House of Lords Act 1999, Caithness, along with most other hereditary peers, lost his automatic right to sit in the House of Lords. He was, however, elected as one of the 90 representative peers designed under the provisions of the act to remain in the House of Lords. According to the Electoral Reform Society, he has since blocked further reform of the Lords, tabling 'wrecking' amendments to a draft Bill to abolish by-elections for hereditary peers, proposed by Lord Grocott in 2018.

Caithness is an opponent of fractional-reserve banking.

Caithness was a trustee of Queen Elizabeth Castle of Mey Trust, from its inception in 1996 until 2016. In 1999, he helped found a heritage charity, the Clan Sinclair Trust, the aim of which is the preservation and conservation of Castle Sinclair Girnigoe, near Wick in Caithness. He serves as chief executive and has been responsible for getting the castle listed by the World Monuments Fund in its Watch List of the 100 Most Endangered Sites in the World in 2002, the fundraising and overseeing the remedial works which has allowed the castle to be accessible and open to the public.

Marriages and children Caithness was married firstly on 9 January 1975 to Diana Caroline Coke. They had two children:

Lady Iona Alexandra Sinclair (born 18 February 1978) Alexander James Richard Sinclair, Lord Berriedale (born 26 March 1981), heir apparent to the earldom.

In January 1994, Caithness resigned from his post at the Ministry of Transport, following the suicide of his wife. In November 2004 he married secondly Leila Cassel Jenkins, whom he had met at Ascot, in Rosslyn Chapel. He filed for divorce a year later. They had no children.
