John MacKay, Baron MacKay of Ardbrecknish

John Jackson MacKay, Baron MacKay of Ardbrecknish (15 November 1938 – 21 February 2001) was a Scottish Conservative and Unionist Party politician.

He started his career as a mathematics teacher, becoming Head of Mathematics at Oban High School.

He was a Tory candidate for the Western Isles in the February 1974 election having, in the climate of the era, accepted he could realise his original Liberal Parliamentary ambitions only by joining the Conservatives. He contested Argyll in October 1974 and was Member of Parliament for the constituency from 1979 to 1983, and after boundary changes, for Argyll and Bute (UK Parliament constituency) from 1983 to 1987, when he lost the seat to the Liberal candidate Hon Mrs Ray Michie - the daughter of Lord Bannerman, a local Liberal.

MacKay was Parliamentary Under-Secretary of State for Scotland from 1982 to 1987 with responsibility for Health and Social Work and was Commons Scottish spokesman on Agriculture (which was the responsibility of the Earl of Mansfield sitting in the Lords). Against the advice of officials he supported a Private Member's Bill on solvent abuse, a scourge of the time, which became law in 1983. In Health he threw himself into the 1982 NHS strikes and a modernisation of mental health legislation.

Following his defeat, he was given a life peerage as Baron MacKay of Ardbrecknish, of Tayvallich in the District of Argyll and Bute. He rejoined the government as a Lord in Waiting in 1993. In January 1994, he joined the Department of Transport as a Parliamentary Under-Secretary of State, being promoted later that year to become Minister of State at the Department of Social Security, a post he held until 1997. During this time he was held in high regard by both the civil servants who worked with him and by the ex-Service community with whom he had regular contact in his role as War Pensions Minister. In opposition, he served as Deputy Leader of the Conservative peers.

He died in 2001 in Wandsworth at the age of 62.
