The diminutive weight-lifter, Precious McKenzie, was a prodigious talent, but apartheid prevented him from competing for South Africa.

Precious had to move to Britain and work in a factory in Northampton.

While doing so, he finally achieved international success at the 1966 Commonwealth Games.

Precious went on to become a familiar figure on British TV in the 1970s.

Emily Williams talks to him for Sporting Witness.
