Eagle-eyed royal fans have spotted King Charles facing pen trouble again while signing the oath at his coronation on Saturday.
The monarch has had a pen problem in the past when he tried to sign visitor’s book at Hillsborough Castle near Belfast.
He had reacted with frustration after the pen he was using leaked on him.
However, the King appeared relieved as he signed the oath without any trouble during the coronation ceremony.
But royal fans spotted Charles was having trouble screwing the lid back onto the pen, appearing to grimace after signing the oath.
King Charles and his wife Queen Consort Camilla were officially crowned by Archbishop of Canterbury Justin Welby in landmark coronation in Westminster Abbey on Saturday.
Charles, 74, automatically succeeded his mother late Queen Elizabeth II as king on her death last September.
