Prince Philip leads way in royal public appearances
The Duke of Edinburgh has spent 51 days this year carrying out public engagements - more than the Duke and Duchess of Cambridge and the Queen.
Prince Philip's appearances with the Queen since the start of 2017 have ranged from feeding an elephant at ZSL Whipsnade Zoo to attending the official opening of the Metropolitan Police headquarters at New Scotland Yard.
Solo engagements by the 96-year-old included opening the new Warner stand at Lord's Cricket Ground in London and meeting actor Tom Cruise at a Buckingham Palace dinner to mark the 75th anniversary of the Outward Bound Trust.
He is scheduled to make his final outing this year on August 2 at a palace parade which would bring his total to 52, pending any other official appearances yet to be confirmed.
The Queen has so far spent 49 days carrying out public engagements since January 1, up to and including July 25.
William has spent 43 days on public events, while Kate has totalled 37.
