Germany is pushing for Greece to relinquish control over its budget policy to European institutions as part of discussions over a second rescue package, a European source told Reuters on Friday. "There are internal discussions within the Euro group and proposals, one of which comes from Germany, on how to constructively treat country aid programs that are continuously off track, whether this can simply be ignored or whether we say that's enough," the source said. The source added that under the proposals European institutions already operating in Greece should be given "certain decision-making powers" over fiscal policy.
