The Prince will give an emotional speech about his late mother, Diana. He will do this on his wedding day. He wanted his mother remembered on his and Kate’s special day. Royal watchers say, he has been practicing for weeks. It’s very emotionally charged. Here’s an excerpt of what William will say:
‘My dear mother is here in spirit and would be proud of Catherine today. Never a day goes by without thinking of my mother, whose greatest wish would be for me to find happiness with a woman I truly loved’ (what Royal watchers say is the gist of the speech, of course, in William’s own words). He will also say something about Catherine qualities are like Diana’s qualities, her kindness and time for others.
