The European Union chose Dominique Strauss-Kahn on Tuesday to head the International Monetary Fund, putting the former French finance minister in line to succeed Rodrigo de Rato in October. Portugal, which leads talks between all 27 EU nations, said Europe would support Strauss-Kahn after Spain's de Rato steps down to spend more time with his family. "We think he would be an excellent managing director of the IMF," said Portuguese Finance Minister Fernando Teixeira dos Santos, who led the talks between the EU nations. Strauss-Kahn, 58, had previously been tipped to challenge unsuccessful French presidential candidate Segolene Royal for the leadership of the Socialist Party. He said he would now work hard to convince other IMF members that he was the right man for the job. "The upcoming period should be one of adapting the IMF to the new order created by the globalization of finance," Strauss-Kahn said. "The mission of the fund will have to be redefined, as will the respective places of different partners, notably in giving emerging countries the role they are due." French Finance Minister Christine Lagarde said Strauss-Kahn's caliber and international experience had allowed him to swiftly win support from other EU nations. Germany's Peer Steinbrueck said he was "the best candidate Europe had to offer." Europe and the United States divide the top jobs at the two major financial institutions, with the EU picking the head of the IMF and the US choosing the World Bank's leader. The IMF board is expected to approve the candidate Europe had chosen. But British Finance Minister Alistair Darling said it was time for the system to change and the post should still be open to candidates from other parts of the world. "We think there needs to be an opportunity for all members of the IMF to make their own assessment as to individual candidates... and then, of course, pick the best candidate for the job," he told reporters. "We don't believe that the situation whereby it is assumed that there will automatically be a European candidate for the IMF just as there is an American candidate for the World Bank is sustainable in the long term." He said Britain would have liked more time to select someone, although he described Strauss-Kahn as a "credible" candidate. Dutch Finance Minister Wouter Bos earlier said it was still an "open race" between Europe and candidates from other parts of the world. Teixeira dos Santos said there was nothing to prevent another candidate from coming forward but that any wider changes should be part of reforms to national voting weights at the IMF and to governance at both the IMF and the World Bank. Lagarde said questioning how the IMF candidate is selected should also mean challenging the US role in picking the World Bank president - picking at a recent wound that saw Europeans unhappy at Paul Wolfowitz's slowness to heed calls to resign from the bank following an ethics scandal. "If this tradition is questioned, it should be for the two institutions at the same time," she said. "Every candidate from every institution will be open to hearing every concern from developing countries." Her German colleague agreed. "After the US could propose the successor for Wolfowitz at the World Bank, I think the current tradition should continue," Steinbrueck said. French President Nicolas Sarkozy had canvassed the United States and other European countries for support for Strauss-Kahn - even though the Socialist earlier said it would be a "betrayal" for him to join Sarkozy's new government. Sarkozy was more generous. "He is France's candidate, but I hope he will be Europe's candidate," he said. Strauss-Kahn thanked Sarkozy on Tuesday, saying support from him and Luxembourg Prime Minister Jean-Claude Juncker - a governor of the IMF - had been decisive in winning EU-wide support for his nomination.
