Wikileaks handed Swiss data by former banker Rudolf Elmer

A former Swiss banker has handed over what he says is evidence of tax evasion by hundreds of corporations and individuals, to the Wikileaks website.

Rudolf Elmer is due to return to Switzerland later this week to face trial for stealing information from the bank.

At a news conference, he said he had handed over the bank details because he was concerned about the use of off shore accounts for tax evasion.
