Henry Campbell-Bannerman

Sir Henry Campbell-Bannerman (né Campbell; 7 September 1836 – 22 April 1908) was Prime Minister of the United Kingdom from 1905 to 1908 and Leader of the Liberal Party from 1899 to 1908. He also was Secretary of State for War twice, in the cabinets of Gladstone and Rosebery. He was the first First Lord of the Treasury to be officially called the "Prime Minister", the term only coming into official usage five days after he took office. He remains the only person to date to hold the positions of Prime Minister and Father of the House at the same time, and the last Liberal leader to gain a UK parliamentary majority.

Known colloquially as "CB", Campbell-Bannerman firmly believed in free trade, Irish Home Rule and the improvement of social conditions, including reduced working hours. A. J. A. Morris, in the Oxford Dictionary of National Biography, called him "Britain's first and only Radical prime minister". Following a general-election defeat in 1900, Campbell-Bannerman went on to lead the Liberal Party to a landslide victory over the Conservative Party at the 1906 general election – the last election in which the Liberals gained an overall majority in the House of Commons. The government he subsequently led passed legislation to ensure trade unions could not be liable for damages incurred during strike action, introduced free school meals for all children, and empowered local authorities to purchase agricultural land from private landlords. Campbell-Bannerman resigned as prime minister in April 1908 due to ill-health and was replaced by his chancellor, H. H. Asquith. He died 19 days later – the only prime minister to die in the official residence, 10 Downing Street.
