World leaders are to continue talks on measures to limit the current financial turmoil at a summit in Washington.

They hope to agree on long-term reforms to cut the risk of further crises and a coordinated economic stimulus plan.

Efforts are focused on five hours of formal talks on Saturday.

 The summit began with a working dinner on Friday.

Divisions have emerged between Europe, which wants stricter market rules and the US and other countries, which prefer more moderate reforms.

Opening the two-day summit at the White House, US President George W Bush dampened hopes for quick solutions.
