ATHENS — A former Greek culture minister, several employees of the Finance Ministry and a number of business leaders are on a list of more than 2,000 Greeks said to have accounts in a Swiss bank, according to a respected investigative magazine. The Greek magazine, Hot Doc, published the list on Saturday, raising the stakes in a heated battle over which current and former government officials had seen the original list passed on by France two years ago — and whether they had used it to check for possible tax evasion.
