The Queen has pulled out of a planned engagement at St. Paul's Cathedral due to illness.
A spokesperson for Buckingham Palace announced the 92-year-old monarch is feeling "under the weather" and will not attend the Thursday morning event.
A statement read: "The Queen is feeling under the weather today and has decided not to attend this morning's service at St Paul's Cathedral marking the 200th anniversary of the Order of St Michael and St George.
"Her Majesty will be represented by The Duke of Kent as Grand Master of the Order."
Further details were not released.
The Queen is feeling under the weather today.
According to The Telegraph, there was no doctor called and The Queen still intends to travel as planned to Windsor this afternoon ahead of a busy calendar of engagements in Scotland next week.
The Queen carried out 154 official engagements in 2017.
Her 97-year-old husband, Prince Philip, the Duke of Edinburgh, retired from official duty in August 2017.
Since then, he has chosen to attend some public events with The Queen, including the marriage of their grandson Prince Harry to Meghan Markle in May.
It's been a busy couple of weeks for The Queen, who attended multiple days at Royal Ascot and hosted numerous functions at Buckingham Palace.
She's also had Trooping The Colour and The Royal Windsor Cup Final, as well as a busy day of engagements with Meghan, the Duchess of Sussex, in Cheshire.
It marked the first time The Queen and Meghan have undertaken a royal engagement together.
