The Queen begins a year of celebrations marking her diamond jubilee. On February 6, 1952, King George VI died in his sleep at Sandringham. His daughter Princess Elizabeth was declared Queen Elizabeth II. Since then, Queen Elizabeth has been England’s oldest monarch and the second-longest reigning sovereign in British history. Celebrations marking the event will centre around the extended weekend of June 2 (the anniversary of the Queens’ coronation) through to June 5.
