James lives at Bagshot Park, a 17th-century estate near Windsor, with his parents.

The 15th in line to the throne, and the youngest grandchild of the late Queen Elizabeth II, he was born James Alexander Philip Theo Mountbatten-Windsor in Surrey on December 17, 2007.

Prince Andrew led the procession of the remaining royals as they arrived at the chapel for the ceremony today. 

Aides have reportedly said that His Majesty's attendance at any event is 'to be hoped for and planned for rather than assumed', as he continues to focus on his health.

Charles's engagement today will be seen as the King making a move to reassure the public following the shock news.

The King has been receiving treatment for an undisclosed form of cancer since early February after he had an operation for an enlarged prostate at the London Clinic.

William is due to return to public duties after his children return to school following the Easter break.

For now, he will continue to balance supporting his wife and family, and maintaining his official duties as he has done since her operation in January. Queen Camilla stood in for the King at the ancient Royal Maundy ceremony in Worcester earlier this week, marking the first time a consort has performed the duty on behalf of the monarch.

Anne Daley, 65, from Cardiff, Wales, held up a Welsh flag when the King arrived said: 'Did you see the smile (Charles) gave me? He pointed at my flag. He had a lovely smile. He looked well. I think he was happy that we've all come.'

She added: 'I wanted to show my support for King Charles and the Princess of Wales who we are all wishing well. We want to show them that we miss them, Wales misses her. She may not be here but she is not forgotten.' 

The Easter Matins Service - as it is officially known - concluded around 11.45am. 

The King was applauded by members of the public as he left St George's Chapel to cries of "Happy Easter". Camilla was presented with a posy of white and yellow flowers by a young boy.
