Emotional moment Prince Harry is reunited with orphan he first met 12 years ago

This is the emotional moment Prince Harry was reunited with the African orphan he first met 12 years ago.

Relebohile Potsane, also known as Mutsu, was just four years old when Harry met him during his gap year in Lesotho in 2004.

Mutsu inspired the royal to set up his charity Sentebale - which translates to Forget Me Not - to help impoverished children.

The pair have kept in touch ever since - but were reunited in an ITV documentary which shows Mutsu now at the age of 15.

As the pair hug, Harry tells Mutsu: "Look at you. Look how big you are now. Good man."

In a touching moment, Harry adds: "I got your letter. Remember the letter you sent me."

When the pair first met they planted a tree at the children's centre Mutsu now calls home.

And more than a decade on, Harry was back to see just how much it had grown.

"Where is our tree?" Harry asks Mutsu before the pair go over to the spot where they were pictured planting a seedling 12 years ago.

"It looks very different to when I was last here," says Harry.

The royal said: "It's great to see that he is so happy. Our tree has survived, it's grown up. The fence that we built is still there.

"Obviously, I would prefer it in a weird way for him not to have been there, and for us to not know where he was.

"Because then we know that he's happy with a family member, but sadly for him that's not the case."

ITV presenter Tom Bradby, who travelled with Harry for a 2004 documentary about Lesotho, again shadowed the prince as he returned to mark 10 years since he set up his charity there.

In tonight's documentary, Harry also speaks about his mother Princess Diana, who died when he was 12.

Now 32, Harry said: "I never really dealt with what had happened. For a huge part of my life I didn't really want to think about it."

He added it his mother's dedication to charity work that inspired him to carry it on and "make something of his life".
