Buckingham Palace announced Her Majesty has sprained her back and was “disappointed” that missed the annual service.
The Palace statement read: “The Queen, having sprained her back, has decided this morning with great regret that she will not be able to attend today’s Remembrance Sunday Service at the Cenotaph.
He tweeted saying that it might be more of a “serious situation” than is being made by palace officials and “there’s something we’re not being told” about her health.
Former Royal Editor of The Sun Duncan Larcombe argued it was “time” for the Queen to “stand down”.
The monarch regards the poignant service as one of the most significant engagements of the year.
It is understood the sprain is recent and unrelated to her medics’ advice to rest.
One said it is “incredibly unfortunate timing and nobody regrets her absence today more deeply.
She will now remain at Windsor Castle and does not require hospital treatment. It is understood she plans to continue with her schedule of light duties over the next week.
