Rudolf Elmer, the boldest whistleblower in Swiss Banking history will be revealing information about the bank account details of 2,000 high net worth individuals and corporations, to Wikileaks in London, tomorrow. British and American individuals and companies are among the offshore clients and Elmer told one newspaper, the list contains about 40 politicians. The release tomorrow occurs just two days before Elmer before he goes to trial in Switzerland. Elmer is the former chief operating officer in the Caymen islands and an employee of the Julius Baer bank, which has accused him of stealing the info. He said he is releasing the information to reveal how the companies and individuals use the Swiss Banks to conceal wealth for tax evasion and other illegal purposes. Elmer is being tried for violating Swiss banking secrecy laws although the data is from the Cayman islands.
