Prince Harry will take part in his first state visit later this month, when the King and Queen of Spain arrive in the UK.
King Felipe and Queen Letizia will stay at Buckingham Palace from 12 - 14 July as guests of the Queen and Prince Philip, but they will be welcomed by a number of royal family members during their visit.
Details released by Buckingham Palace today confirmed Harry will escort the Spanish royals on a trip to Westminster Abbey on the third day of their trip.
The King will lay a wreath at the Grave of the Unknown Warrior before they are given a tour of the Abbey, including the Tomb of Eleanor of Castile.
On arrival in London, the guests will receive an impressive royal welcome.
Following a ceremony at Horse Guards Parade, the King and Queen will be given a state carriage procession along the Mall to the Palace, where they will have a private lunch with the monarch.
Later, they will travel to Clarence House for tea with Prince Charles and the Duchess of Cornwall before they return to the Palace for a state banquet. Although the Duke and Duchess of Cambridge have not been given official roles, it's thought they could be among the guests at the dinner.
Following meetings with Theresa May and the Spanish ambassador, a visit to Oxford University and talks with business leaders in the capital, the couple's visit will end when they return to Spain on Friday 14 July.
Queen Letitia of Spain has a lot in common with Prince Harry's girlfriend, Meghan Markle, as both have enjoyed successful careers before enjoying romances with their respective royal beaus (Letitia a journalist and Meghan an actress) and both have previously been divorced.
News of Harry's involvement in the state visit comes after the Queen and Prince Philip announced they would be taking on fewer royal duties. In recent months, senior royals including William and Kate have stepped in to support the Queen.
Later in July, the Duke and Duchess will go on a five-day tour of Poland and Germany. Best of all, Kensington Palace has confirmed the public can expect to see Prince George and Princess Charlotte 'on at least a couple of occasions over the course of the week'.
