After apparently spending a night in hospital last week, the Queen skipped worship on Sunday.
Her Majesty, 95, who rarely misses church, had to cancel a two-day trip to Northern Ireland last week at the last minute due to medical test results.
The monarch is expected to lead the Royal Family to the COP26 summit in Glasgow next Monday, according to advisers, who claim the security checks are merely precautionary.
On Sunday, the pious king is said to have had private prayers with a chaplain within Windsor Castle. Her health has been questioned when she attended 120 public events in the 194 days after Prince Philip’s death.
Palace sources told The Sun she is unlikely to be seen this week as she has been told by medics to only carry out light duties.
author Angela Levin is ‘delighted’ the monarch decided against prayers at Windsor’s All Saints Chapel yesterday. She says it shows she is ‘perhaps listening and agreeing to temporarily step back’.Ms Levin said: ‘She is very religious and it is very important personally for her to go to church every Sunday.
‘But she has to come out of the nice little bubble she has at Windsor Castle, get in and out of cars and up and down in church. It is all exhausting.
‘It is very sensible to give it a miss so she can do more in the future.’The Queen’s stay at King Edward VII’s Hospital in London on Wednesday was her first overnight stay at a hospital in eight years. In 2013, she was treated at the same private clinic for gastroenteritis.
