The Queen and Duke of Edinburgh have marked their 73rd wedding anniversary by releasing a photograph showing them opening a card from the Duke and Duchess of Cambridge's children.
The picture taken earlier this week shows the monarch and Prince Philip sitting on a sofa in Windsor Castle's Oak Room looking relaxed as they look at the card from Prince George, Princess Charlotte and Prince Louis.
The colourful homemade gift was created by their great-grandchildren and features a number 73 that pops out from the front of the card.
On a nearby table, there is also a small pile of anniversary cards and letters sent by well-wishers.
The photo, taken by Chris Jackson from Getty Images, joins a collection of thousands of pictures taken over the decades documenting the history of their enduring relationship.
The monarch, 94, was a 21-year-old princess when she married Lieutenant Philip Mountbatten at Westminster Abbey on 20 November 1947. They have been married longer than any British sovereign and consort.
The Queen and the duke, who has retired from public duties, are currently spending lockdown at Windsor Castle.
There is no traditional gift, jewel or colour associated with 73rd wedding anniversaries in the UK.
But in the new photograph, the Queen is wearing a chrysanthemum brooch made from sapphires and diamonds set in platinum.
She wore the same brooch when she was photographed on her honeymoon at Broadlands in Hampshire in 1947, and again in pictures released to mark the Queen and duke's 60th wedding anniversary in 2007.

On their golden wedding anniversary in 1997, the Queen paid a touching tribute to her husband, saying: "He has, quite simply, been my strength and stay all these years."
Philip used the occasion to praise the Queen for her abundance of tolerance.
"I think the main lesson that we have learnt is that tolerance is the one essential ingredient of any happy marriage," he said.
