US: THE sudden resignations of Sotheby's chief executive Diana 'Dede' Brooks and chairman Alfred Taubman have come in the wake of the investigation into alleged commission fixing which has seen the company's stock plummet by 60 per cent since the start of this year.

Christopher Davidge, who led Christie’s International throughout the 1990s and steered it from public to private ownership in 1998, has stepped down. His position as chief executive has gone to Edward Dolman, who has been running Christie’s in America since last summer.

Sotheby’s chief executive Bill Ruprecht has also become chairman of the company with immediate effect following Michael I. Sovern’s decision to step down after 13 years.
