Prince Philip will no longer carry out public engagements beginning this fall.
Buckingham Palace said in a statement issued early Thursday that the 95-year-old prince has the queen's full support in his decision to step back from royal duties.
The palace says Philip will attend engagements until August and that Queen Elizabeth will continue to carry out a full program of public engagements.
The palace statement followed hours of speculation about the health of the queen and her husband after Britain's Daily Mail reported on an "unusual meeting of royal household staff."
Elizabeth and Philip appeared to be in good health on Wednesday.
The queen met with British Prime Minister Theresa May at the palace and Philip made an appearance at a London cricket club.
