The Queen will attend her first royal engagement since lockdown was introduced to celebrate her official birthday.
The occasion is normally marked by the Trooping the Colour ceremony, but the parade was cancelled due to the coronavirus restrictions.
But as the UK begins to ease lockdown, Buckingham Palace has confirmed that a small military ceremony will be staged at Windsor Castle in honour of the Queen.
It is hoped the Monarch will attend the "unprecedented" celebrations, but it's unclear whether other members of the Royal Family will travel from their lockdown bases to attend.
However Prince Philip, who is self-isolating with the Queen at Windsor and celebrates his 99th birthday a few days before the ceremony, could be watching on.
The new event will be held on Saturday, June 13 and will involve troops from the Welsh Guards who will perform a royal salute in the castle's quadrangle, reports the Daily Mail.
They claim the service will be shown on the BBC but well-wishers will not be able to attend.
A palace spokesman confirmed the new anniversary celebration, saying: "There will be a small, brief military ceremony at Windsor Castle to mark the Queen's official birthday."
Shortly after lockdown was announced, the Palace announced the traditional Trooping the Colour had been cancelled.
It's just the second time in the Queen's reign that the service, which always takes place in June, has not gone ahead.
It famously features a gathering of the royal family on Buckingham Palace's balcony to acknowledge the crowds in The Mall and watch a flypast.
Trooping also attracts thousands of spectators, friends and family of the soldiers taking part in the military spectacle, who fill stands around Horse Guards Parade in Whitehall where the event is normally staged.
The Queen hasn't been seen since the Commonweath Day Service at Westminster Abbey on March 9, which was Meghan Markle and Prince Harry's final royal engagement as senior royals.
The family has followed government guidelines and have been working from home, limiting their interactions with members of the public and their charity contracts to Zoom calls and letters.
