Wills and Harry’s big cat adventure as Princes greet a cheetah in Botswana

Princes William and Harry today met school children in Botswana to promote environmental awareness.

The brothers visited the Mokolodi Education Centre, near a 4,500-hectare nature reserve in Maun, on the second day of their first joint tour.

They laughed as they wrapped a rock python around their necks, with Harry, 25, pointing the snake's head towards his brother's head.

William, 27, is patron of the Tusk Trust, an African heritage charity that works closely with the wildlife centre.

The brothers are using their six-day trip to show each other the work of their charities.

Their next stop is the mountain kingdom of Lesotho, where Harry will take William to see projects run by his charity, Sentebale. to help Aids orphans. On Friday, they will watch the England-Algeria match in South Africa on the invitation of the FA.

The princes have both talked of their emotional attachment to Africa, which they picked up from their late mother, Diana.

The brothers have taken only four aides on the visit and their security is expected to be stretched when they spend 24 hours apart later in the tour.

They last travelled together two years ago when they joined a charity motorcycle ride in South Africa from Port Edward to Durban.

Harry is on a break from his helicopter training with the Army Air Corps and has spent the past few weeks on holiday in southern Africa with friends.
