The Duke and Duchess of Cambridge and Prince Harry have been made official ambassadors for Team GB and Paralympics GB in the run-up and during the 2012 London games.
Their new role will see Kate, William and Harry promote British athletes and they will play an active role in encouraging the public in supporting the sports men and woman taking part.
It is likely the trio will visit the teams over the coming months before the Olympics begin next July and the Paralympics a month later, and also have some involvement in the global competitions.
"Catherine, Harry and I are honoured to be ambassadors for Team GB and ParalympicsGB," William said.
"London hosting the 2012 Olympic and Paralympic Games will inspire so many people - particularly the young - to be the best they can be.
"We are hugely looking forward to this incredible sporting competition, but are also looking beyond next summer's Games to the springboard it will provide for future success and excellence."
The London Olympics begin July 27 and end Aug. 12.
