Do you know who presided over the setting up of the National Health Service, or who served the shortest time as leader? Read our timeline of British prime ministers of the 20th century for all the answers.

Robert Gascoyne-Cecil 3rd Marquess of Salisbury
Conservative 1895 to 1902
Salisbury was the last peer to serve as PM (this was his third tenure), with the brief exception of Douglas Home (below) who renounced his peerage within a few days of being appointed.

Arthur James Balfour
Conservative 1902 to 1905
Balfour was the nephew of the Marquess of Salisbury but his cabinet was divided on the issue of free trade and without the support of Edward VII he was forced to resign in December 1905.

Sir Henry Campbell-Bannerman
Liberal 1905 to 1908
Following Arthur James Balfour’s resignation, Edward VII invited the leader of the next largest party, Sir Henry Campbell-Bannerman, to form a government. He was the first leader to officially use the title of ‘Prime Minister’.

Herbert Henry Asquith
Liberal 1908 to 1916
Asquith is the only Prime Minister to have taken office on foreign soil. At the time that he succeeded Campbell-Bannerman, Edward VII was in Biarritz so Asquith travelled there for the official ‘kissing-hands’ ceremony.

James Ramsey MacDonald
Labour 1929 to 1935

Chamberlain famously declared “I believe it is peace for our time” following a meeting in 1938 with Adolf Hitler.

Harold Wilson
Labour 1964 to 1970
Wilson won his first election in 1964 but he actually visited 10 Downing Street many years before, when he was eight-years-old, so his aspirations began early.

Grammar school educated Heath served in the Second World War, reaching the rank of Lieutenant Colonel.
