PARIS (Reuters) - French police widened an investigation
into a trading scandal at Societe Generale
The brokerage, a SocGen subsidiary formerly known as Fimat but renamed this year after it merged with Calyon Financial, executed some of Kerviel's trades.
Investigating magistrates have dropped fraud accusations from the charge sheet.
The appeal hearing is due to be heard from 1300 GMT on Friday.
Societe Generale accuses Kerviel of unauthorized trades which led to a record 4.9 billion euros ($7.17 billion) loss when it closed out his positions.
Kerviel told the Agence France Presse news agency in an interview on Tuesday that he accepted his share of responsibility for the losses but did not want to be made a scapegoat.
Societe General is working on a 5.5 billion euros rights issue to repair its balance sheet after the trading losses and write-downs linked to the U.S. subprime mortgage crisis. The rights issue is expected to be launched next week.
