During her televised address to the nation, the Queen will also pay tribute to the Duke of Edinburgh, who has retired from solo public duties, praising his “support and unique sense of humour”.
The Queen’s message to the nation and the Commonwealth will look back over the previous 12 months and take “home” as its theme.
In her pre-recorded address, filmed at Buckingham Palace, the Queen will say: “This Christmas, I think of London and Manchester, whose powerful identities shone through over the past twelve months in the face of appalling attacks.”
The nation endured a series of devastating terrorist atrocities during the year, beginning with the Westminster Bridge attack in March that saw four pedestrians die when an attacker, later shot dead by police, drove at them before fatally stabbing a police officer.
In Manchester a few months later 22 people – including children – were killed when a lone suicide attacker detonated an explosive device as crowds of music fans left Manchester Arena following a performance by US singer Ariana Grande.
There were more deaths in June when three terrorists in a van ploughed into pedestrians on London Bridge then went on a knife rampage in Borough Market, killing eight in total. They were shot dead by police.
The address traditionally has a strong religious framework reflecting the Queen’s faith, and is written by the monarch who draws on current issues and her own experiences over the past year.
Philip, famed for his quips, inquisitive mind and “no-fuss” attitude, stood down from his solo public role in August, although he has made the occasional appearance at events involving the Queen.
Speaking about the Christmas message’s theme the Queen will say: “We think of our homes as places of warmth, familiarity and love… there is a timeless simplicity to the pull of home.”
This year’s annual address has been produced by Sky News and was recorded in the palace’s 1844 room which is decorated with a large tree and features family photos.
Pictures of the Queen’s great grandchildren, Prince George and Princess Charlotte, can be seen, along with two wedding related images of the Queen and Philip – but taken 70 years apart.
The royal couple are featured in a black and white image from their 1947 wedding, and in a colour photo released to mark their 70th wedding anniversary celebrated in November.
In the broadcast the Queen is wearing an ivory white dress by Angela Kelly, an outfit she first wore with a matching coat and hat for the Diamond Jubilee Thames River Pageant in 2012. She is also wearing a star-shaped diamond brooch.
