LONDON: The G20 is expected to promise this weekend to keep economic support packages in place until recovery is certain and seek to reassure financial markets they have credible plans to withdraw the stimulus when appropriate.

Finance ministers and central bankers from the Group of 20 developed and emerging nations are meeting in London to discuss the economic outlook, curbs on bank bonuses, tighter financial regulation and reform of international institutions.

Since their leaders met in April in the midst of the worst global recession since the Great Depression, prospects for the world economy have improved with growth returning in a number of countries and stock markets powering ahead.
