The Queen was advised by her doctors to rest for the next two weeks and only take on “desk tasks”, Buckingham Palace said.
The development comes after the Queen underwent hospital tests last week and canceled a two-day trip to Northern Ireland.
But the head of state has “firm intention” to lead the nation in honoring the country’s war dead on Memorial Sunday, November 14th.
In a statement, Buckingham Palace said: “Following her recent advice that the Queen should rest for a few days, Her Majesty’s doctors have recommended that she should continue to rest for at least the next two weeks.
“Doctors have indicated that Her Majesty may continue to perform light desk duties during this time, including some virtual audiences, but no official visits.
“Her Majesty regrets that she will not be able to attend the commemoration on Saturday November 13th.
“However, it remains the Queen’s firm intention to attend the National Memorial Service on Memorial Sunday, November 14th.”
