European Union governments are wrestling over how to help Greece, whose debt crisis has shaken the EU and undermined the shared euro currency, AP reported. Officials said Wednesday that the burden was on Greece to show markets details on how it can cut its massive debt, even as public sector workers strike to protest an austerity program. Greek Prime Minister George Papandreou is pledging to «take any necessary measures» to reduce Greece's deficit. But German officials said Wednesday there was no urgent need for a bailout at the moment and that «no decision on such help» is imminent. They also said EU rules prohibited them from guaranteeing another country's debts. «Of course, we are running through worst-case scenarios,» a German official said on condition of anonymity. «Greece has to present a credible volume of cuts. Agreement on that would be an important signal from tomorrow's summit.» Markets are looking for more _ a plan on what EU nations would do if Greece were near a default. Stephen Lewis, an analyst at Monument Securities, said financial markets «are taking it for granted that support will be forthcoming and would probably react negatively if the summit's outcome fell short of expectations.» -- SPA
