Fifty years ago, two 200m runners set the Olympics in Mexico City alight by giving Black Power salutes on the podium as they collected their medals.

The pair had no shoes on - to represent those living in poverty - and had human rights logos on their jackets, which Australian silver medalist Peter Norman wore as well. They both say there is still a great deal more to be done to tackle racism.
