ere days before a crucial E.U. summit in Brussels, Greece's finance minister has resigned for health reasons. Vassilis Rapanos, chairman of the National Bank of Greece, was named finance minister last week, but submitted his resignation following a hospital admission for intense abdominal pain, nausea, sweating, and dizziness. "After discussion with my doctors, I reached the conclusion that the state of my health, currently, will not allow me to fully and adequately exercise my duties," he said. Prime Minister Antonis Samaras, who accepted his resignation, also will be unable to travel to the summit, as he is recovering from eye surgery. The news comes amidst yet another tumultuous day for the eurozone, with Cyprus announcing that it will apply for a bailout and Spain making a formal request for billions of euros in aid for its banking sector.
