Queen Elizabeth II Becomes The Longest-Reigning British Monarch: A Life In Pictures

    As Queen Elizabeth II becomes Britain’s longest-reigning monarch after beating Queen Victoria’s record of 63 years and 216 days on the throne, we take a look at her reign in pictures.

    Princess Elizabeth was born at 2.40am on 21 April 1926. She was the first child of the Duke and Duchess of York, who became King George VI and Queen Elizabeth. After King George VI died, his wife became Queen Elizabeth the Queen Mother.
