NEW YORK (CNNMoney) -- European leaders insist they are making progress on a comprehensive plan to tackle the eurozone's debt and banking crisis.
But the details are foggy and last-minute delays suggest that significant disagreements remain unresolved.
On Wednesday, government heads from all 27 members of the European Union will gather for a second time, following a summit over the weekend.
"The sovereign debt crisis threatens the very existence of the eurozone," said Howard Archer, chief European economist at IHS Global. "It is therefore absolutely imperative that European policymakers finally deliver a major package."
