World leaders to reach agreement

World leaders will strive to reach an agreement on how to confront the worst global financial crisis since the 1930s at the G20 summit in London.



They are looking at ways to revive the world economy and at how to strengthen the financial system to prevent a repeat of the crisis in the future.



The BBC reports that rifts exist between key players but there are signs that an agreement is close.



More demonstrations are expected after protests in London\'s financial district yesterday.



The summit is being held, amid tight security, at the Excel Centre in London\'s Docklands.



In the run-up to the summit, the main differences have been between France and Germany, who are seeking stricter regulation of the financial system, and the UK and US, who think extra government spending would do more to ease the crisis.
