August 2, 2017 marks Prince Philip’s final royal appointment when he attends a Royal Marines charity parade.
The 96-year-old Duke of Edinburgh is officially retiring after 65 years of public service.
According to The Telegraph, Philip has carried out 22,219 solo engagements and 637 solo visits overseas since he left active military service in 1952.
In retirement, the Duke will likely enjoy more leisure time at Windsor Castle in Berkshire – he is an avid carriage driver and enjoys oil painting.
His Royal Highness will be remembered equally for his sharp wit as he will be for his gaffes, which have often left the nation laughing or reeling.
The Prince's prolonged service has won him support from both sides of Parliament, though. Jeremy Corbyn applauded his "clear sense of public duty" and Theresa May praised his "steadfast support" to the Queen.
Philip's lengthy career, marked by hundreds of visits to far-flung corners of the British Empire, has unsurprisingly produced some remarkable royal photography. So, here are the best images from each of his 70 years as Prince Philip, Duke of Edinburgh:
