In October 1968, two American sprinters, Tommie Smith and John Carlos, staged one of the most iconic protests in sport at the Mexico City Olympics. The two athletes raised their gloved fists in the air at the medal ceremony for the 200 metres as a way of protesting against racism. Simon Watts reports. The programme was first broadcast in 2016.
