Tony Blair was sounded out on the candidacy of Paul Wolfowitz to lead the World Bank before the White House announced his nomination but did not share the controversial proposal with cabinet colleagues or fellow European leaders.

The British prime minister was informed about Mr Wolfowitz's possible candidacy and relayed to Washington that he would not oppose him. The issue was raised with Mr Blair when Condoleezza Rice, the US secretary of state, visited London last month, according to two senior US officials close to the proceedings. Mr Blair's discreet support gave President George W. Bush the confidence to know that Mr Wolfowitz, the deputy defence secretary and an advocate of the war in Iraq, would not face united opposition from the World Bank's European shareholders.
