Corrections: Ken Powell; Thilo Sarrazin

* Ken Powell, chief executive of General Mills, said Americans spend $1,000bn (a trillion dollars) on food each year, not $1bn as wrongly published in the View from the Top interview on October 30. * A photograph of Thilo Sarrazin, a board member of the Bundesbank, was wrongly identified as Axel Weber, Bundesbank president, in an article on October 30. We apologise for these errors.
