(ANSAmed) - ATHENS, DECEMBER 3 - An official with the Greek financial crimes squad SDOE has reportedly said that Margaret Papandreou, mother of former Prime Minister George Papandreou, is involved with a deposit of 550 million euros in the Geneva, Switzerland branch of HSBC, the biggest on a list of 2,059 Greeks with accounts there who haven't been checked for tax evasion. She - as GreekReporter remembers - is also the former wife of the late Andreas Papandreou, a former Prime Minister who was George Papandreou's father. George Papandreou resigned as Premier a year ago after two years of ceaseless protests, strike and riots against austerity measures he imposed on the orders of international lenders. He later gave up the head of the PASOK Socialists party his father co-founded. The depositor is reportedly a civil servant named Maria Panteli, but according to the Greek newspaper To Vima, Nikolaos Lekkas, the Manager-Comptroller of SDOE, said that, ''Behind the biggest deposit on the list is Mrs. Margarita Papandreou.'' The list was originally given by then French Finance Minister Christine Lagarde - now the head of the International Monetary Fund, one of Greece's lenders - to former Finance Minister George Papanconstantinou, who said it went missing. Now called 'The Lagarde List,' it details names of Greek depositors that were included on a larger list of names throughout Europe that was stolen from the bank by an employee. (ANSAmed).
