The board said it was clear that a number of people had erred in
reviewing Riza's pay package.
Wolfowitz said he consulted the bank' ethics board about Riza.
As a result of the controversy, the board pledged to review the World

robust to the strain under which they were placed."
The board said it would immediately begin searching for a successor.
By tradition, the World Bank has been run by an American. The Bush
administration keenly wanted to keep that decades-old practice firmly
intact as the board dealt with Wolfowitz's fate. The United States is
the bank's largest shareholder.
