Mr Burnand, 59, has been taking royal portraits for more than 20 years and was behind the lens for the official shots after the weddings of both the then Prince of Wales and Camilla Parker Bowles at Windsor Castle in 2005 and Prince William and Catherine Middleton at Buckingham Palace in 2011.

He told the Telegraph it was a “family moment” adding of the portraits: “We keep it nice and tight and cosy.”

In his message, the King said: “As the Coronation weekend draws to a close, my wife and I just wanted to share our most sincere and heartfelt thanks to all those who have helped to make this such a special occasion.

“We pay particular tribute to the countless people who have given their time and dedication to ensuring that the celebrations in London, Windsor and further afield were as happy, safe and enjoyable as possible.

“To those who joined in the celebrations – whether at home, at street parties and lunches, or by volunteering in communities – we thank you, each and every one.”

He added: “To know that we have your support and encouragement, and to witness your kindness expressed in so many different ways, has been the greatest possible Coronation gift, as we now rededicate our lives to serving the people of the United Kingdom, the Realms and Commonwealth.”

The message was signed Charles R.
