The Duke of Edinburgh is 85 today and is marking his birthday privately at Windsor Castle. Royal Anecdotes wishes Prince Philip a very happy birthday and many entertaining returns.

Among the itinerary of celebration, a 41-gun salute will be fired in Hyde Park by the King’s Troop in Prince Philip’s honour.

Public involvement in the Duke’s personal milestone will take place next week. On June 15, the Massed Bands of the Royal Marines will perform a Beating Retreat on London’s Horse Guards Parade in honour of the Prince and he will take the salute.

Earlier on the same day, the Duke will join the Queen at a national service of thanksgiving at St Paul’s Cathedral to mark her official 80th birthday.
