Queen Elizabeth will become the world’s second longest ruling monarch on Sunday (June 12), surpassing King Bhumibol Adulyadej of Thailand whose reign lasted 70 years, 126 days before his death in 2016 at the age of 88.
The 96-year-old Elizabeth, Britain's longest-reigning and currently the world's oldest monarch, became queen on February 6, 1952.
On September 9, 2015, Queen Elizabeth surpassed the 63 years, that her great-great-grandmother Queen Victoria spent on the throne to become the country's longest-reigning monarch in a line dating back to Norman King William the Conqueror in 1066.
Queen Elizabeth's seven decades on the throne was marked by four days of celebration which began on Thursday (June 2) and saw the nation come together, rejoicing in the Queen's 70 years and four months reign.
