The Queen is officially the longest ever reigning monarch in British history after passing the record set by her great-great-grandmother Queen Victoria.
As of today, the Queen will have ruled for more than 63 years and 216 days.
Princess Elizabeth became Queen Elizabeth II when she was 25 upon the death of her father King George VI, who died in the early hours of 6 February 1952.
The coronation of Queen Elizabeth II as monarch took place at Westminster Abbey on 2 June 1953.
The milestone is sure to be well received in the Vale where the Queen has been a regular visitor over the years, and as recently as last year.
That most recent visit, back in February 2014, saw Her Majesty enjoy a lunch of Scottish smoked salmon, lamb, potatoes, vegetables, bread and butter pudding and ice cream with the Prime Minister.
David Cameron had invited Her Majesty to Chequers near Wendover for what was only her third visit to the countryside retreat in 40 years.
Mr Cameron said he thought it would be a good opportunity to invite the Queen to have lunch with him and to host her for a change.
She famously graced Aylesbury with her presence back on Friday May 10 2002 as part of her Golden Jubilee.
She was in the Vale again in 2007, when she went to Stowe School near Buckingham, to open a new girl’s boarding house, before touring the National Trust gardens.
And the trip culminated with them planting two trees close to where Queen Victoria and Prince Albert planted a pair of trees in 1845.
