When Rudolf Elmer, a former employee of a Swiss bank, stood on a stage in London and handed a CD to Wikileaks founder Julian Assange this January, a shiver might have gone down the spine of many high net worth individuals.
Elmer was passing on the private financial details of 2,000 British, American and German clients of the bank Julius Baer, where he worked until 2002, covering the period from 1990 to 2009. Although it was not revealed what information Elmer passed on, he has previously handed information to Wikileaks that shed light on what it alleges is tax evasion.
