The Queen will deliver what is expected to be a particularly personal Christmas Day message surrounded by reminders of the Duke of Edinburgh, as she prepares to spend her first festive period without her late husband.
A photograph released by Buckingham Palace ahead of her televised address to the nation shows the Queen sitting behind a desk in the White Drawing Room at Windsor Castle.
Next to her is a framed picture of her and Philip taken in 2007 at Broadlands country house, Hampshire, to mark their diamond wedding anniversary.

The handout picture shows the Queen wearing an embossed wool shift dress in Christmas red, by British designer Angela Kelly, as well as a chrysanthemum brooch which the then-Princess Elizabeth wore for a photocall on her honeymoon, also to Broadlands, in 1947.
The Queen also wore the brooch, made from sapphires and diamonds set in platinum, in a photo to mark the couple's 73rd wedding anniversary last year.
She is sat in front of an illuminated Christmas tree.
This year's message follows the death of the duke in April aged 99, while coronavirus restrictions at the time meant the Queen was memorably and poignantly forced to sit alone in St George's Chapel for his funeral service.
Buckingham Palace announced the Queen had agreed to stage a service of thanksgiving for the life of the duke next spring, with the date and guestlist yet to be finalised.
The Queen is expected to be joined at Windsor Castle on Christmas Day by the Prince of Wales and the Duchess of Cornwall, having shelved her customary trip to Sandringham as a "precautionary" measure amid rising coronavirus cases.
But the Duke and Duchess of Cambridge will be spending Christmas in Norfolk and will be joined by some members of the Middleton family.
The Queen used her 2020 Christmas broadcast to deliver a heartfelt message of hope to the country, praising the "indomitable spirit" of those who had risen "magnificently" to the challenges of the coronavirus pandemic.
The Queen's address to the nation will be broadcast across multiple channels at 3pm on Christmas Day including BBC One, ITV, Sky One, Sky News and to listen on BBC Radio 4.
