Prince Harry said he 'won't rest' until he's made the world a better place for his children Lilibet and Archie.

The Duke of Sussex was speaking to 'Kindercorrespondent' or so-called child reporters during the during the Invictus Games at The Hague when he commented on his plans.

He said he will "never, ever, ever rest" until he has made the world a better place, adding: "Because it is our responsibility that the world is the way it is now,'

"I don't think that we should be bringing children into the world unless we're going to make that commitment to make it better for them. We cannot steal your future."

It comes after Harry spoke sweetly about his son Archie and what he wanted to be during a speech at the games yesterday.

After being introduced by Meghan to the stage, Harry said: "To be role models, or the role models, that each of you are takes strength and it takes courage.

“When I talk to my son Archie about what he wants to be when he grows up, some days it’s an astronaut, other days it’s a pilot – a helicopter pilot obviously. Or Kwazii from Octonauts. If you’re laughing then you’ve seen that.

“But what I remind him is that no matter what you want to be when you grow up, it’s your character that matters most, and nothing would make his mum and me prouder than to see him have the character of what we see before us today.”
