Sir Robert Walpole is regarded as the first British prime minister, taking up the responsibilities and duties of the chief political minister for Britain in 1721. However, his official title was 'First Lord of the Treasury' (a title still held by today's PM's); the term 'prime minister' was not officially recognised until 1905.
Since Sir Robert Walpole, there have been a further 50 men (and one woman) who have become Prime Minister, and we have listed them here for you below, along with the dates they took office, and their political party.
