Prince Harry and Meghan have sent a touching birthday message to the Queen on her 93rd birthday.
The Duke and Duchess used their new Instagram account to post a series of throwback snaps of the monarch – and some showing Harry in his younger days.
Expectant parents Harry and Meghan were among those wishing her well, writing on Instagram: “Happy Birthday Your Majesty, Ma’am, Granny. Wishing you the most wonderful day! Harry & Meghan.”
Elizabeth II, who has a strong faith and is head of the Church of England, usually celebrates Easter at Windsor Castle by joining members of her family at a service in St George’s Chapel.
At Buckingham Palace, the Band of the Irish Guards will perform a rendition of Happy Birthday in her honour on the forecourt as part of the Changing of the Guard ceremony.
April 21 – the day the Queen was born – is the first of the monarch’s two birthdays.
The Queen also celebrates her ‘official’ birthday in June, which is marked with the Trooping the Colour parade.
Gun salutes are also fired as a mark of respect to the Queen – though never on a Sunday, so this year they will be delayed by one day.
Tomorrow, the King’s Troop Royal Horse Artillery will ride their horses and gun carriages past Buckingham Palace en route to Hyde Park to stage a 41 Gun Royal Salute at noon.
A 62-gun salute will also be performed by the Honourable Artillery Company at the Tower of London at 1pm the same day.
The Queen traditionally spends a month-long residence at Windsor Castle, known as Easter Court, each year.
Princess Elizabeth Alexandra Mary was born at 2.40am on April 21 1926, the first child of the then Duke and Duchess of York, at 17 Bruton Street, the Mayfair home of her mother’s parents, the Earl and Countess of Strathmore.
She was never expected to be Queen, though the abdication of her uncle Edward VIII in 1936 resulted in her father George VI taking the throne, and changed her path for good.
Elizabeth II, who has been monarch for more than 67 years, is Head of State, the Armed Forces and the Commonwealth, and has been married to the Duke of Edinburgh for more than 71 years.
She became Britain’s longest-reigning monarch, passing her great-great grandmother Queen Victoria’s record, in September 2015.
Following the death of 88-year-old King Bhumibol Adulyadej of Thailand in 2016, the Queen currently holds the record for the world’s longest-reigning living monarch.
