Sir Winston Leonard Spencer Churchill, (30 November 1874 – 24 January 1965) was a British statesman who served as Prime Minister of the United Kingdom from 1940 to 1945, during the Second World War, and again from 1951 to 1955. Best known for his wartime leadership as Prime Minister, Churchill was also a Sandhurst-educated soldier, a Nobel Prize-winning writer and historian, a prolific painter, and one of the longest-serving politicians in British history. Apart from two years between 1922 and 1924, he was a Member of Parliament (MP) from 1900 to 1964 and represented a total of five constituencies. Ideologically an economic liberal and imperialist, he was for most of his career a member of the Conservative Party, which he led from 1940 to 1955, though he was a member of the Liberal Party
