G8 leaders look to block spread of EU debt crisis

Leaders of major industrial economies are meeting this weekend to try to tackle a full-blown crisis in Europe where fears are growing that Greece could leave the eurozone bloc, threatening the future of the common currency.

US President Barack Obama, the G8 host, has urged European leaders repeatedly to do more to stimulate growth, fearing contagion from the euro crisis could hurt the US economy and his chances of re-election in November.

British Prime Minister David Cameron, who has been increasingly vocal in urging Europe to do more to resolve the debt crisis, will tell leaders they must work together to stop it from spreading worldwide, an aide said.
