World Bank President Paul Wolfowitz and his bank-employed girlfriend will appear before a special panel on Monday to discuss a promotion and raise he arranged for her that has sparked calls for his resignation.
"He will be appearing on Monday morning and making a full presentation to the committee, showing them that there is absolutely no merit at all in the allegation that there was a conflict of interest," Wolfowitz's lawyer, Robert Bennett said.
Mr Bennett will be present but will not be allowed to address the committee, which was appointed by the World Bank's board of shareholder nations last week to look into whether Wolfowitz breached ethical or other rules by approving a promotion for his girlfriend, Shaha Riza.
Mr Bennett said he was notified by Victoria Toensing, a lawyer for Ms Riza, that her client would also address the committee.
Mr Wolfowitz has faced increased pressure to step down as the controversy over the promotion reached fever pitch at the bank, where some staff have openly voiced deep concern that the issue has undermined their work in eradicating poverty.
The former Pentagon second in command and Iraq war architect has apologised for how he handled the promotion. He has said he was new to the job and acted on the advice of a board ethics committee to deal with the issue in a "practical way."
The issue has been a lightning rod for broader unhappiness over Mr Wolfowitz's appointment to the bank in 2005 and his management style. Many longtime World Bank employees accuse him of relying heavily on the advice of a coterie of aides he brought with him from the Pentagon and White House.
Earlier this week, Mr Wolfowitz complained he was being treated "shabbily and unfairly without regard to appropriate process" when the committee refused to allow Mr Bennett to address its members, and he asked for more time when the panel gave him less than 24 hours' notice to appear.
