The Queen has today made history as she became the first British monarch to reach their Sapphire Jubilee.
On February 6, the anniversary of the day she became Queen, Elizabeth II will have reigned for 65 years.
She is expected to commemorate the landmark date privately at her Sandringham Estate, Norfolk, with no official engagements planned.
Royal gun salutes will be staged in London on Ascension Day, as is the tradition, with a 41-gun salute by the King’s Troop Royal Horse Artillery in Green Park at noon.
The Queen, who missed church over Christmas due to a heavy cold, will may well be matter-of-fact about the historic occasion.
In 2015, when she thanked the nation for its kind messages after overtaking Queen Victoria to become the longest-reigning monarch in British history, she admitted the royal record was “not one to which I have ever aspired”.
She added: “Inevitably, a long life can pass by many milestones. My own is no exception.”
The Queen celebrated her 90th birthday last year, with activities including a walkabout, beacon lighting and a black tie dinner for family and friends in Windsor on her actual birthday.
A weekend of national celebrations, including a party on The Mall, was held for her official birthday in June.
It is likely that any large-scale jubilee celebrations will be reserved for the Platinum Jubilee in 2022 – although any events will take into account the fact that Queen is due to turn 96 that year.
The Duke of Cambridge will this summer become a full-time royal, increasing his official duties on behalf of the Queen.
