Nelson Mandela's granddaughter has launched an augmented reality expedition highlighting the forgotten stories of black Britons.
As of today people travelling into central London, and those not in the Capital with a mobile phone, can use Snapchat to find out the black history behind Trafalgar Square's monuments.
Unveiled with Mandela’s granddaughter, Tukwini Mandela, the AR experience will be permanent and has been timed to coincide with the release of the South African leader's release from Robben Island 32 years ago.
