New Delhi, Nov 2 (IANS): Prime Minister Manmohan Singh left for Cannes in the French Riviera Wednesday to attend the 6th G20 Summit where the focus will mainly be on how to resolve Europe's sovereign debt crisis.

The two-day summit Thursday-Friday is also expected to take stock of the progress on other matters discussed earlier, like mutual assessment of the fiscal policies of member nations and reform of World Bank and International Monetary Fund, officials said.

Like in the past five summits held in Washington, London, Pittsburgh, Toronto and Seoul, Planning Commission Deputy Chairman Montek Singh Ahluwalia will be the prime minister's sherpa, or chief interlocutor, during the meeting.

The prime minister returns Saturday morning.

The G20, originally formed at the level of finance ministers and central bank governors in 1999 after the East Asian economic crisis, assumed significance after its elevation to a summit-level forum in 2008, following the global financial crisis.

Besides India and host France, the G20 comprises Brazil, US, Canada, China, Argentina, Australia, South Korea, Germany, Indonesia, Italy, Japan, Mexico, Russia, Saudi Arabia, South Africa, Turkey, Britain, and the European Union.

These members account for 80 percent of the global gross domestic product and two-thirds of the world population.
