Bundesbank President Axel Weber told German lawmakers that Greece may need more aid than the 30 billion euros ($40 billion) promised by the European Union as the government in Athens struggles to push through planned spending cuts, two people present at the briefing said.

Weber, citing television footage of Greek demonstrators, expressed concern that sections of the Greek population either don’t care or fail to appreciate the seriousness of the situation their debt-laden country faces, the two people said. They spoke on condition of anonymity because the briefing in Berlin yesterday was held in private.

Bundesbank spokeswoman Susanne Kreutzer declined to comment on Weber’s presentation.
