Princes remember final call with Diana

It was a typical phone call between two boys and their mother, who was on vacation in France. It was brief; the boys wanted to get back to playing with their cousins, not spend time on the phone chatting.

The brevity of that 1997 call haunts Prince William and Prince Harry to this day, for their mother, Princess Diana, would die in a car crash that night.

“Harry and I were in a desperate rush to say goodbye. You know, ‘See you later.’ If I’d known now, obviously, what was going to happen, I wouldn’t have been so blase about it and everything else,” William says in a new documentary. “But that phone call sticks in my mind, quite heavily.”

Harry says in “Our Mother: Her Life and Legacy,” which aired Monday on British TV, that the final chat is something he will regret forever.

“It’s incredibly hard. I’ll have to sort of deal with that for the rest of my life,” Harry says. “Not knowing that was the last time I was going to speak to my mum. How differently that conversation would have panned out if I’d had even the slightest inkling her life was going to be taken that night.” William was 15 at the time. Harry was 12. William says he frequently tells his children — Prince George, 4, and Princess Charlotte, 2 — about Diana so she can be a presence in her grandchildren’s lives.

“She’d be a lovely grandmother. She’d absolutely love it, she’d love the children to bits,” he says.
