Queen Elizabeth has pulled out of a royal engagement last minute due to her health.
A statement from Buckingham Palace was issued announcing The Duke of Kent would take Her Majesty's place at a commemorative church service being held in London.
'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,' the Palace said.
'Her Majesty will be represented by The Duke of Kent as Grand Master of the Order.'
The 92-year-old monarch's health concerns are not believed to be major, with a spokesperson telling Telegraph UK that no doctor or hospital was involved.
Her Majesty still plans to travel to Windsor in the afternoon, where she'll spend the weekend before heading to Scotland as planned early next week, for a number of engagements there.
Her Royal Highness underwent surgery last month to remove a cataract from her eye, Buckingham Palace announced earlier.
Her Majesty 'successfully underwent a short planned procedure', a spokesman from the palace said.
