Queen Elizabeth's birthday will not be marked by a gun salute this year

The ritual was scrapped last year in line with the queen's wishes that no "special mesasures" were taken while the UK remained in the grip of lockdown amid the coronavirus pandemic.

According to the Daily Mail newspaper, plans to mark the queen's birthday with a new portrait have also been abandoned.

The monarch is expected to mark her birthday with a quiet private lunch with close family members at Windsor Castle, with the royal family's various social media channels expected to be the only public outlet commemorating the day.

It had been claimed even before Philip's death that the queen hadn't wanted her birthday to be marked in a meaningful way because she wanted to focus instead on the Duke of Edinburgh's 100th birthday, which he would have celebrated on 10 June.

The queen's birthday parade, Trooping the Colour, was scheduled for 12 June but in March was cancelled for the second consecutive year due to the global health crisis.

Before Philip passed away, Buckingham Palace had instead been considering a smaller event like the "mini Trooping", which was held at Windsor Castle last year, led by the Welsh Guards and massed Bands of the Household Division, but it is now unclear if those plans will still go ahead.

The annual Garter service, also usually held in June, has also been cancelled.

The queen is not expected to take on any public engagements in the next few weeks, but it has been confirmed she will be present for the state opening of parliament on 11 May, with Prince Charles set to accompany her to the Palace of Westminster.
