The British Army has swiftly removed a claim on its website that Catherine, the Princess of Wales, will attend a Trooping the Colour ceremony in June.
That engagement would have been the first appearance announced for the 42-year-old royal since she underwent abdominal surgery.
The announcement by the Ministry of Defence caused confusion, because Prince William and Kate’s office, Kensington Palace, had not confirmed any scheduled public events for Kate.
The BBC reported that the Army did not seek approval from the palace before publishing the page, which had a picture of Kate and copy stating she would be reviewing troops on 8 June.
Kate has been out of the public eye since January, when palace officials announced that she was admitted to a private London hospital for planned surgery.
They didn’t provide more details, but said that she wouldn’t return to public duties until after Easter.
