Oprah's £20m ($40m) school proves she's not all talk

Oprah Winfrey, the talk show star and media mogul, likes to make friends through generosity, famously once giving every member of her studio audience a free car to take home. Yesterday, however, she celebrated giving of a slightly less frivolous kind.

Surrounded by American celebrities, Winfrey, listed as the richest black person on the planet, presided over the opening of a school for disadvantaged girls just outside Johannesburg, South Africa, built with $40m (£20m) of her own money and set to begin classes on Friday.
