The Duke of Edinburgh will continue the association he has with charities, but will no longer play an active role in attending engagements, Buckingham Palace has said.
The palace announced this morning that Prince Philip, who is patron, president or member of more than 780 organisations, including many charities, will retire from royal duties in the autumn.
Engagements in his diary before he retires include presenting an award at London Zoo at the end of June.
Robert Meadowcroft, chief executive of Muscular Dystrophy UK, said Prince Philip had been patron of the charity for more than 50 years.
"We cannot thank him enough for his active support, which has been a precious asset in the fight against muscle-wasting conditions," he said.
He said the duke had helped to raise awareness and promote understanding of the cause and had met hundreds of people and families who struggle to live with muscular dystrophy.
Alison Tweed, director of Book Aid International, said: "His royal highness has been a wonderful patron for us for more than 50 years, giving us a great sense of continuity in the charity as we have changed and developed and grown.
"He has always been interested in what we are doing, with his very own strong views, and supporting the work that we do."
John Low, chief executive of the Charities Aid Foundation, said the charity had greatly benefited from the duke’s support as patron.
"The royal family plays a vital role in supporting charities and encouraging people to give," he said. "Many of us might not have heard of some of these remarkable charities if it were not for the royal family’s enduring commitment to them."
