Summit on the eurozone crisis: What is at stake?

EU leaders are to hold another summit by Wednesday, because they will not be able to agree a rescue plan for the euro on Sunday.

French President Nicolas Sarkozy and German Chancellor Angela Merkel said a crisis strategy would be discussed on Sunday and adopted at the next meeting.

EU leaders need to agree a second bailout for Greece, how to recapitalise banks and a stronger bailout fund.
