Campbell-Bannerman had actually become prime minister on 5 December 1905, when Balfour’s Conservative government resigned from office. After the dissolution on 8 January 1906, CB led the Liberal Party to its greatest ever election victory with 400 seats.
CB was the oldest person to become prime minister for the first time in the 20th century, at the age of 69 and the only prime minister to have died at 10 Downing Street. He resigned the premiership on 3 April 1908 in very poor health, but was allowed to stay in the prime minister’s residence by his successor, Asquith. Campbell-Bannerman died at number 10 on 22 April 1908.
Today CB is an almost forgotten figure. He would have rivalled Clement Attlee in the modesty stakes, but Sir Henry Campbell-Bannerman deserves to be remembered for his landslide election victory and for presiding over a hugely talented cabinet containing Asquith, Lloyd George, Grey and Haldane.
