Prince Harry, Meghan Markle visit Nelson Mandela exhibition in London

Prince Harry and his wife Meghan have visited an exhibition in London charting the life of Nelson Mandela.

Peter Hain, a former anti-apartheid campaigner and chair of the Nelson Mandela Centenary Exhibition, said it was "very fitting" for the royal couple to visit because Harry does charitable work in southern Africa, and Meghan has said that Mandela is one of her heroes.
