Prince Harry has returned to Africa on a solo visit.

The 33-year-old royal - who is patron of Rhino Conservation Botswana and president of African Parks - left his fiancée Meghan Markle at home to head to the continent "for a private working trip".

A Palace source told PEOPLE that Harry would be taking in "organisations working in conservation, particularly those affecting wildlife, across the region."

The flame-haired prince is said to have been to Chobe Game Lodge, Kasane, this week, where he met Tshekedi Khama, the minister for environment and natural resources, conservation and tourism.

The insider insisted it is a "short trip", and Harry is expected to head to Botswana - where he sourced the central diamond in Meghan's engagement ring - early next week.

Harry also took the former 'Suits' star to the continent in August to celebrate her 36th birthday, and is said to have treated her to a £1,200-a-night stay in the Tongabezi Lodge resort in Zambia to end their romantic break.

A guide said at the time: "We treat everyone the same. It doesn't matter if you're Prince Harry or anyone else.

"We knew someone important was coming to stay last week but I didn't know it was the Prince until they arrived.

"The Honeymoon House and the Nut House are the ones usually used by couples but I'm afraid I'm not at liberty to let you know which one they used.

"Couples who visit us usually stay in one of those and then spend a night or two at our rooms on an island in the river, which is only accessible by boat. We have several different rooms here at Tongabezi - the family units are different from what a honeymooning couple would want, for example."

Harry is known to be a huge fan of Africa, having visited the continent since he was a teenager, and admitted last year he feels more like himself there than "anywhere else".

He said: "This is where I feel more like myself than anywhere else in the world.

"I have this intense sense of complete relaxation and normality here."
