Henry Campbell-Bannerman was a Liberal politician and prime minister from 1905-8. He was invited by Edward VII to form a government when Balfour resigned in December 1905. In the subsequent general election the Liberals won a large majority, but many of their measures passed in the Commons were defeated by the Conservative majority in the House of Lords - a continuing provocation that led to the Parliament Act of 1911, in which Campbell-Bannerman"s successor, Herbert Asquith, clipped the wings of the upper chamber.
