Britain's Prince Philip Marks Final Public Engagement With Royal Marines Parade

All smiles, the royal tipped his hat while greeting those around him.

During the event, Prince Philip will also meet veterans and cadets before receiving the 1664 Global Challenge baton.

Buckingham Palace said that, as far as they are aware, the Duke's first solo public engagement was on March 2, 1948, when he went to the London Federation of Boys' Clubs Boxing Finals at the Royal Albert Hall.

According to calculation by Buckingham Palace, Prince Philip has undertaken 637 solo overseas visits, delivered 5,496 speeches, and found time to write 14 books and carried out the role of patron for 785 organisations during his royal career.

Elizabeth has called Philip, her husband of nearly 70 years and the longest-serving consort in British history, "my strength and stay". Since 1952 - when Queen Elizabeth II's father passed away and she ascended the throne - Prince Philip has carried out over 22,000 solo engagements, in addition to attending events alongside Queen Elizabeth.

Prince Philip was admitted to hospital three times in nine months between December 2011 and August 2012 and spent 11 days in hospital care because of a bladder infection in 2015.

Earlier today, the U.K.'s The Telegraph accidentally published an article announcing Prince Philip's death.

The announcement in May that the Duke was stepping down came after a day of speculation that the steadfast companion of the Queen for 70 years may have died.

As the Queen's husband of almost 70 years, Prince Philip is the longest-serving British consort (companion to the sovereign).

He 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. Jeremy Corbyn applauded his "clear sense of public duty" and Theresa May praised his "steadfast support" to the Queen.

To mark the occasion, they posted a picture of the Prince alongside his wife, Queen Elizabeth II.

While the Guardian hit upon a story idea of the secret plan in place for when the Queen eventually dies, called "London Bridge is Down", The Independent has put out a broad plan on what happens when Prince Philip dies.
