Britain’s Queen Elizabeth, 92, is feeling unwell and will not attend a special service today at St Paul’s Cathedral, Buckingham Palace said.

“The queen is feeling under the weather today and has decided not to attend this morning’s service ... marking the 200th anniversary of the Order of St Michael and St George,” a palace statement said.

“Her Majesty will be represented by The Duke of Kent as Grand Master of the Order,” it added.

In 2016, she missed the annual Christmas service she usually attends with her family on her estate in Sandringham, eastern England, due to a heavy cold.

Elizabeth was born on April 21, 1926, and became queen in 1952 at the age of 25, meaning she has now reigned for more than 66 years.

While some members of the royal family have been criticized for leading lives of luxury, Elizabeth is widely admired in Britain for her quiet devotion to duty over many decades.
