The Queen is planning to rest at Windsor Castle in the run up to the end of 2021, carrying out only light duties for the rest of the year.
On Sunday, the monarch missed the Remembrance Sunday service at the Cenotaph.
The Queen, who is believed to have suffered a sprained back, has also cancelled an appearance at the General Synod on Tuesday, marking the first time she will have missed her five-yearly visit to the Church’s national assembly in its 51-year history.
While she is set to refrain from any major real-life appearances in the coming weeks, the Queen is scheduled to carry out virtual audiences later this week.
It comes after the Queen was told to rest by the doctor after being admitted to hospital for preliminary investigations on 20 October, marking her first overnight stay in a medical facility in eight years.
This time of year is typically a busy one for HRH who, in November and December 2019, visited the new headquarters of the Royal Philatelic society in London and went to Chatham House, alongside Sir David Attenborough.
She also went to the State Opening of Parliament and would traditionally host the annual white tie Diplomatic Corps reception in December for more than 1,000 guests, an event which has not yet been confirmed for this year.
The Queen would also typically host a pre-Christmas lunch with members of the royal family in the week prior to Christmas Day, after which she would head to Sandringham and remain there until February.
