Her Majesty’s 90th Birthday Party will be a celebration of The Queen’s life, her love of horses, her dedication to the Commonwealth and international affairs and her deep involvement with the Navy, Army and Air Force.
QEII turns 90 today, already the longest reigning monarch in British history.
Elizabeth II is, and has been since her accession in 1952, Queen of the United Kingdom, Canada, Australia, and New Zealand, and Head of the Commonwealth. She is also Queen of 12 countries that have become independent since her accession: Jamaica, Barbados, the Bahamas, Grenada, Papua New Guinea, Solomon Islands, Tuvalu, Saint Lucia, Saint Vincent and the Grenadines, Belize, Antigua and Barbuda, and Saint Kitts and Nevis.
Official events to mark The Queen's milestone birthday tomorrow began in earnest with visits today to the Royal Mail and Alexandra Gardens in Windsor.
According to The British Monarchy Facebook page : "The day began with the release of a commemorative photograph from an institution which also celebrates a big birthday this year: the Royal Mail, which turns 500 this year. The Queen marked the joint birthdays with a visit to the Royal Mail delivery office in Windsor where she met long-serving staff and learnt more about the organisation's daily operations.
The Queen and The Duke of Edinburgh then went on to Alexandra Gardens where Her Majesty opened the new Bandstand.
Celebrations will continue on Her Majesty's actually birthday tomorrow, on 21 April, and in June, when she marks her official birthday.
Thank you Windsor for the wonderful reception for The Queen and Duke today; we look forward to seeing you tomorrow!"
The British Monarchy also shared the Queen's words : "I send my best wishes to those who are celebrating their ninetieth birthday on 21 April 2016. On this shared occasion, I send my warm congratulations to you all. Elizabeth R."
The Prime Minister of the United Kingdom, David Cameron also shared: "The whole country will want to wish the Queen a happy birthday today - she has been a rock of strength for our nation."
"Rarely has anyone in public life served for so long, served so brilliantly and worked so hard. Happy birthday, Your Majesty."
