The account, which documents the engagements of the Duke and Duchess of Cornwall, posted an incorrect message explaining how Prince Charles and Camilla joined the Queen along with other members of the royal family for the service.

The tweet in question read: "Thank you, Your Majesty, for 70 years of unwavering and dedicated service. Their Royal Highnesses, along with other members of The @RoyalFamily, joined The Queen at @StPaulsLondon for a Service of Thanksgiving in this, her #PlatinumJubilee year."
However, this was written in error as the Monarch decided to pull out of the service after feeling some "discomfort" after the Trooping the Colour on Thursday.

The tweet has since been removed and been replaced by a re-written note, explaining how the future King and Queen Consort joined "other members of the Royal Family".
The post also features various images of the royals outside St Pauls ahead of the service, as well as one showing them walking down the aisle at the grand cathedral, with the Duke and Duchess of Cambridge just in front of them, before taking their seats for the service.
On Thursday evening, it was announced by Buckingham Palace that the Queen would not be attending due to feeling "discomfort". A statement explained that Her Majesty "greatly enjoyed her birthday celebration and the flypast in London during the Trooping the Colour parade.
