One year on from the royal wedding, Prince William has spoken about the happiest and the hardest day of his life.
Opening up to ABC journalist Katie Couric, the Duke of Cambridge spoke about the fact that his mother, Princess Diana was not present the day he married Kate Middleton.
In his first interview on the subject, the Prince detailed his sadness that his mother would never get to meet his wife, now Catherine the Duchess of Cambridge, and said he prepared himself emotionally before the big day.
"It was very difficult. I had prepared myself beforehand so that I was sort of mentally prepared, I didn't want any wobbling lips going on," he said.
