The dependence of Greek banks on the European Central Bank continued to drop in February, according to figures released by the Bank of Greece on Thursday. These showed that sums borrowed by Greek banks from the ECB fell to 90.4 billion euro in February 2011, from 94.4 billion euro in January 2011. The Bank of Greece has asked highstreet banks to submit plans that will gradually 'wean' them from dependence on capital supplied by the ECB by mid-May.
