Will's brother, Prince Harry has had a few words to say in reaction to the birth of his nephew. Speaking to the BBC at a photographic exhibition in London documenting the work of his Lesotho charity Sentebale, Prince Harry said it was "fantastic to have another addition to the family", and that the newborn "was crying his eyes out" when he met him.
