The Queen is set to become Britain’s longest serving monarch next month, surpassing the record of her great-great grandmother Queen Victoria.
Queen Victoria ruled for 23,226 days, 16 hours and 23 minutes, a record Queen Elizabeth II - currently in residence at Balmoral - will pass on September 9.
Palace officials have said the momentous date will pass without celebration, with official plans instead focusing efforts on Her Majesty’s 90th birthday next year.
Currently, the world’s longest living serving monarch is King Bhumibol Adulyadej of Thailand, who has reigned for the past 69 years.
Historically, the world’s longest serving monarch was King Sobhuza II of Swaziland, who reigned for 82 years, having ascended the throne at the age of one, dying in 1982.
The shortest serving monarch of all time was Louis Antoine of France, Duke of Angouleme, who served for just 20 minutes - the time it took him to sign resignation papers following the abdication of his father.
The shortest serving British Monarch was Lady Jane Grey, who served for nine days before being beheaded by her cousin for treason in 1553. She is said by Leicestershire school children to haunt the ruins in Bradgate Park, where it is widely believed she was born.
