Apartheid South Africa looked after white people and nobody else. Now some of its white communities face a growing and often violent crisis which threatens their future in the country.

Some estimate that across the country there may be up to 400,000 poor white people living in squatter camps with little or no water or electricity.

BBC World Affairs Editor John Simpson, who once lived in South Africa, examines the challenges facing white South Africans - despite their continued disproportionate influence on the country's economy and media.

"They still have the best houses, and most of the best jobs," he said. "Look below the surface and you will find poverty and a sense of growing vulnerability."
