The summit of the world’s leading countries next weekend is unlikely to produce radical change in the way the global economy is governed, according to the head of the International Monetary Fund.

Comparisons between the November 15 summit and the Bretton Woods conference in 1944 which created the fund were overblown, said Dominique Strauss-Kahn, the IMF’s managing director. The most the summit could achieve would be to bring together analysis already done and set working groups in motion for agreements further down the line, possibly in six months or so.
