Queen Elizabeth II will not attend the Remembrance Sunday service at the Cenotaph in central London, a commemoration of the country's war dead, due to a back sprain, according to Sky News.
The Queen is deeply disappointed that she must miss the engagement, and hopes to continue as planned with a schedule of light duties next week, the palace said in a statement.
The 95-year-old monarch had cancelled a trip to Northern Ireland in October after doctors advised that she rest for a few days ahead of medical exams. She spent a night in hospital.
Elizabeth II also cited medical recommendations when she opted not to attend the United Nations' COP26 climate change conference in Glasgow in person.
