Prince Charles and his wife Duchess Camilla are currently holidaying in Greece.
Duchess Camilla and Prince Charles
The royal couple have spent the past few days visiting tea rooms and stopping by breweries as part of their annual tour of the UK, but they'd seemingly had enough of the wet weather battering British soil on Tuesday (02.08.17) as they were spotted on board super-yacht OKTO, which was owned by the Greek millionaire Theodore Angelopoulos, in the European country, according to the Express newspaper.
But while Charles was soaking up some sun with his wife, his father Prince Philip was carrying out his last ever official engagement on behalf of the royal family.
The 96-year-old royal - who announced his upcoming retirement earlier this year - hosted a parade at Buckingham Palace in honour of the finale of the Royal Marines 1664 Global Challenge as his last official solo duty for the crown.
It was a fitting ceremony to mark his retirement as the Duke of Edinburgh is the Captain General of the Royal Marines and a former Royal Navy officer.
The event's name recognises the year the Royal Marines were founded, and the ceremony marked the end of the 1664 Global Challenge, which sees marines push themselves to the limit with a series of physical exploits in aid of the Royal Marines Charity.
Queen Elizabeth's beloved husband appeared chirpy as he inspected the troops, before he stepped onto a podium and waved his bowler hat to the cheering crowds.
The MailOnline reports that he also chatted to physical training instructor, Sergeant Matt Burley, who swam 1,664 lengths underwater over 10 days and Lieutenant Colonel Aldeiy Alderson, who ran 100 kilometres in 12 hours wearing his Royal Marines uniform and polished boots.
And he made the marines laugh when he quipped: "You all should be locked up."
Prince Philip has carried out 22,219 solo engagements since 1952, and Prime Minister Theresa May took to Twitter to thank him for "a remarkable lifetime of service".
She added that she hoped he "can now enjoy a well-earned retirement".
Though he will no longer be summoned to attend solo royal engagements, the royal may accompany the Queen at certain events in the future.
