Later today, Queen Elizabeth II will become the UK's longest-reigning monarch, surpassing her great-great grandmother Queen Victoria.
Her 63-year reign equates to 23,226 days on the throne and in typical fashion, the Queen is hoping to keep the day very low-key.
The Sun's veteran royal photographer Arthur Edwards spoke to Paul Henry this morning about his favourite memories of the royal family.
Edwards was there through numerous events during the Queen's reign – from meeting three different popes, visiting the White House, shaking hands with Nelson Mandela and meeting Mother Theresa – not to mention when the Queen had eggs thrown at her in New Zealand.
