Ahead of the G-20 Summit, Planning Commission Deputy Chairman Montek Singh Ahluwalia will lead a delegation to a preparatory meet on March 11 in London where deliberations on issues like liquidity crunch and reforms in international financial institutions are likely be taken up.

"Beside Ahluwalia, the RBI Governor D Subbarao and Economic Affairs Secretary Ashok Chawla will participate in the G-20 sherpas meeting with their counterparts of the other member nations," a senior government official said.

Issues like completion of Doha Round, the global liquidity problem, cooperation between all the central banks and credit problems of exporters would be discussed, he said.

Prime Minister Manmohan Singh, who recently underwent a successful coronary artery bypass surgery, is likely to attend the G-20 London Summit on April 2, hosted by British Prime Minister Gordon Brown.

The world leaders at the London Summit would emphasise that all countries renounce protectionism, with a transparent mechanism to monitor commitments and measures to increase access to trade finance, agree for reform of financial regulation and international financial institutions and honour commitments to increase development assistance to protect the poorest from the impact of the crisis.

While the focus of the Summit would be on jobs, financial stability and security and terrorism issues would also figure in the discussion.
