Princes William and Harry are teaming up to launch a new initiative on behalf of their grandmother, Queen Elizabeth II.
On Wednesday at Buckingham Palace the brothers will unveil details of The Queen's Young Leaders Programme which aims to find future Commonwealth leaders.
The Queen is the head of the Commonwealth - the voluntary association of 53 countries made up of 2.2 billion citizens - and the position will one pass to William.
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.
He added: "It is vital that younger generations learn the lessons of the war by visiting memorials like St Symphorien near Mons, lest we forget".
