Prince Philip's final official Royal engagement before retirement has been announced.
The Duke of Edinburgh, who turned 96 in June, will attend a parade at Buckingham Palace on 2 August to mark the finale of the Royal Marines 1664 Global Challenge.
The parade will mark the end of the Challenge, which raises money for The Royal Marines Charity.
Prince Philip became Captain General of the Royal Marines in 1953, replacing King George VI after his death.
Buckingham Palace announced in May that the Duke would give up his official public duties this year so he could enjoy "more leisure time".
A palace spokeswoman said the parade would:
"bring His Royal Highness's individual programme to a conclusion, although he may choose to attend certain events, alongside the Queen, from time-to-time".
It is believed that Princes Charles, William and Harry are now expected to increase their workload.
Prince Philip became the longest-serving consort in the British monarchy's history in 2009 and is the oldest ever male member of the British Royal Family.
