Prince William has spoken out for the first time since his nan's funeral on Monday, via a video call to a gathering in New York.
The new Prince of Wales had been due to attend the Earthshot Prize Innovation Summit and said it is due to the "saddest of occasions" that he couldn't be there in person.
William was to make the solo trip to the United States on September 21, where he would have been joined by previous winners of his £50 million global environmental competition.
