In his testimony, Mr. Greenblatt listed as oil-voucher recipients Benon Sevan, who headed the U.N. office overseeing the oil-for-food program; a Russian politician, Vladimir Zhirinovsky; a former French interior minister, Charles Pasqua; a British Labour parliamentarian, George Galloway, and a Syrian journalist, Hamidah Na'na.

Mr. Zhirinovsky and Mr. Galloway were vociferous advocates for the lifting of U.N. sanctions. Investigators said the Iraqi government allocated 80 million barrels of oil to Mr. Zhirinovsky, and they released a copy of a letter written by the Russian inviting an international oil company to Moscow to negotiate to buy oil allocated to him.

The Russian, along with other foreign politicians named in recent weeks as oil voucher recipients, denied any wrongdoing. Last month, Mr. Annan said he didn't believe the Security Council had been influenced or bought in any way by the ousted Iraqi dictator.
