Prince William and Prince Harry

Britain's Prince William and Prince Harry will unveil a new initiative on behalf of the Queen.

The royal brothers have teamed up to launch the 'The Queen's Young Leaders Programme' - a scheme devoted to finding new commonwealth leaders - at Buckingham Palace on Wednesday (08.07.14), where they will personally deliver all the details associated with the initiative on behalf of their grandmother, Queen Elizabeth II, reports Hello magazine.

It isn't the first time the pair have undertaken royal duties on behalf of the 88-year-old monarch.

During her diamond jubilee celebrations in 2012, the pair travelled worldwide to attend royal engagements, with Prince William, 32 and his wife Duchess Catherine visiting Malaysia, Singapore and the Solomon Islands and Prince Harry, 29, attending events in Jamaica, Belize, and The Bahamas.

The heir to the throne - the Prince of Wales - was also called on to represent the Queen at the Commonwealth Heads of Government Meeting in Sri Lanka in November last year, following a review of the amount of long-haul travel the monarch was undertaking.

The Princes and the Duchess of Cambridge, 32, will also travel to the St Symphorien Military Cemetery - a Commonwealth War Graves Commission cemetery near Mons, Belgium - next month, where they will take part in a commemorative event to mark the centenary of the First World War.

British ambassador to Belgium, Jonathan Brenton, said: "I am absolutely delighted that The Duke and Duchess of Cambridge and Prince Harry are coming to Belgium for the First World War Centenary commemorations this August.

"These commemorations remind us of the important bond between our two countries and the sacrifices we shared together one hundred years ago.

"It is vital that younger generations learn the lessons of the war by visiting memorials like St Symphorien near Mons, lest we forget".
