World Bank president Paul Wolfowitz is digging in for the fight. Wolfowitz is under pressure to quit with the investigation into the way his girlfriend, Shaha Riza, got a pay rise and promotion.

A day after an investigation into the sordid little affair was announced, Wolfowitz hired lawyer Robert Bennett.

Now, where we have we heard that name before? Bennett is the attorney who represented former US president Bill Clinton against sexual harassment claims by paula Jones.

More details from BusinessWeek.

In the meantime, a group of former World Bank executives have written a letter to the Financial Times saying Wolfowitz should go:

"We believe that he can no longer be an effective leader. He has lost the trust and respect of Bank staff at all levels, provoked a rift among senior managers, developed tense relations with the Board, damaged his own credibility on good governance -his flagship issue, and alienated some key shareholders at a time when their support is essential for a successful replenishment of the resources needed to help the poorest countries, especially in Africa ... There is only one way for Mr Wolfowitz to further the mission of the Bank: he should resign.
