Andrew Bonar Law (/ˈbɒnər ˈlɔː/; 16 September 1858 – 30 October 1923) was a British statesman and politician who was Prime Minister of the United Kingdom from October 1922 to May 1923.
Law was born in the British colony of New Brunswick (now a Canadian province). He was of Scottish and Ulster Scots descent and moved to Scotland in 1870. He left school aged sixteen to work in the iron industry, becoming a wealthy man by the age of thirty. He entered the House of Commons at the 1900 general election, relatively late in life for a front-rank politician; he was made a junior minister, Parliamentary Secretary to the Board of Trade, in 1902. Law joined the Shadow Cabinet in opposition after the 1906 general election. In 1911, he was appointed a Privy Councillor, before standing for the vacant party leadership. Despite never having served in the Cabinet and trailing third after Walter Long and Austen Chamberlain, Law became leader when the two front-runners withdrew rather than risk a draw splitting the party.
