Prince William reveals that having children brought back "emotions" of Princess Diana's death

The Duke of Cambridge has revealed that the "life-changing" experience of having children brought back the emotions he felt following the death of his mother, Princess Diana.

In a new BBC documentary, Prince William - who has Prince George, six, Princess Charlotte, five, and Prince Louis, two - opened up about how having children is "one of the most amazing moments in life, but also one of the scariest" when having lost one's own parent.

Speaking to former soccer star Marvin Sordell for the Football, Prince William And Our Mental Health documentary, he e said: "Having children is the biggest life-changing moment, it really is.

"And I agree with you, I think when you've been through something traumatic in life - and that is like you say your dad not being around, my mother dying when I was younger - your emotions come back in leaps and bounds because it's a very different phase of life.

"And there's no one there to, kind of, help you, and I definitely found it very, at times, overwhelming."

The 37-year-old went on to reveal he and his wife Kate Middleton rely on one another for support when they experience those "overwhelming" feelings. 

William was 15 and his brother, Prince Harry, was 12 when their mother died in a Paris car crash in 1997.
