• The Queen was set to attend a Remembrance Sunday event in London on Sunday.
• She pulled out of the event about two hours before it was set to start, citing a sprained back.

Queen Elizabeth II pulled out of an event on Sunday less than two hours before it was due to begin, citing a sprained back.

"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. Her Majesty is disappointed that she will miss the service," a Buckingham Palace spokesperson told Insider in a statement.

The service is to commemorate Britain's war dead.

"As in previous years, a wreath will be laid on Her Majesty's behalf by The Prince of Wales. His Royal Highness, along with The Duchess of Cornwall, The Duke and Duchess of Cambridge, The Earl and Countess of Wessex, The Princess Royal and Vice Admiral Sir Tim Laurence, The Duke and Duchess of Gloucester, The Duke of Kent and Princess Alexandra will be present at the Cenotaph today as planned."

The event is due to start shortly before 11 a.m. local time (6 a.m. ET) Sunday.

The 95-year-old monarch had already canceled several in-person royal engagements for weeks, citing her doctors' advice.
