The Queen will reflect on the hardships of the pandemic in her Christmas speech later, as she and the Duke of Edinburgh spend the day apart from their family.
They will celebrate Christmas at Windsor Castle and not Sandringham, as is their usual tradition.

The Royal Family usually spends the day together, but will not visit each other this year because of restrictions.
The Queen will also forgo her usual church service and worship privately to avoid crowds, it is understood.
Her Christmas Day speech will be broadcast at 15:00 GMT.
The Queen, 94, and Prince Philip, 99, have been living at Windsor Castle during the pandemic with a small household staff.
It is thought to be the first time the couple have not spent Christmas at their Sandringham home since the mid-1980s.
