Richard Law, 1st Baron Coleraine

Lady Coleraine died on 3 April 1978 in Helensburgh, Scotland. Lord Coleraine died on 15 November 1980, age 79, and was succeeded in the barony by his son James Martin Bonar Law.

In 1970, Lord Coleraine published another book, For Conservatives Only, in which he criticised the Conservative leadership of the time for, in his view, sacrificing Tory principles for electoral expediency and the pursuit of the "middle ground". At this time he was Patron of the Selsdon Group of Conservative MPs.

Through his elder son James, he was a grandfather of Hon. Elizabeth Mary Law (b. 1961), who married Charles Ironside, 3rd Baron Ironside (only son and heir of Edmund Ironside, 2nd Baron Ironside) in 1985; Hon. Sophia Anne Law (b. 1964); Hon. James Peter Bonar Law (1975-2019), Hon. Henrietta Margaret Law (1968–1993), and Hon. Juliana Caroline Matilda Law (b. 1971). Through his son Andrew, he was a grandfather of Richard Pitcairn Bonar Law (b. 1963) and Charlotte Mary de Montmorency Law (b. 1964).

Law was again elected as an MP in the election of 1951, this time for Haltemprice, but he resigned this seat in January 1954 and in February was elevated to the House of Lords as Baron Coleraine of Haltemprice in the East Riding of the County of York. After his elevation to the peerage, he went on a two-week lecture tour in the United States, following two weeks in Russia at the invitation of the Russian government.

In 1950, Law published Return from Utopia, a book in which he stated his belief that trying to use the power of the state to create any sort of Utopia is not just unattainable but positively evil, because one of the first principles to be sacrificed is the principle of freedom and individual choice. Law argued:

He was then Minister of State, also at the Foreign Office, until 1945, when he served briefly as Minister of Education in Churchill's caretaker government. In a by-election in November 1945 he became MP for Kensington South, which he held until February 1950.

Law was elected as Member of Parliament (MP) for Kingston upon Hull South West in the general election of 1931 and held the seat until 1945. In 1940 he was appointed Financial Secretary to the War Office. He was then transferred to the post of Parliamentary Under-Secretary of State for Foreign Affairs until 1943. While in the latter post he took part in the Bermuda Conference on the fate of European Jewry and was sworn of the Privy Council in the 1943 New Year Honours.

On 26 January 1929, Lord Coleraine (when still Richard Law) married Mary Virginia Nellis, the second daughter of Abraham Fox Nellis, of Rochester, New York. Her father, a silk manufacturer, had died in 1923. Together, they were the parents of two children:

He was the youngest son among six children born to businessman and Conservative politician Bonar Law (who would go on to serve as Prime Minister of the United Kingdom from 1922 to 1923) and Law's wife, the former Annie Pitcairn Robley, a daughter of Harrington Robley, a merchant from Glasgow.

Richard's brother Charlie, a lieutenant in the King's Own Scottish Borderers, was killed at the Second Battle of Gaza in April 1917, followed by brother James, a captain in the Royal Fusiliers, who was shot down and killed on 21 September 1917. His sister Isabel married Sir Frederick Sykes, and another sister Catherine married The 1st Baron Archibald in 1961.

Richard Kidston Law, 1st Baron Coleraine, PC (27 February 1901 – 15 November 1980) was a British Conservative politician.
