The holes in slice of Swiss Cheese isa bout to leak.

LONDON — A Swiss banker whose actions caused a U.S. judge to briefly shut down WikiLeaks three years ago has promised to hand over a trove of banking secrets to the secret-spilling organization on Monday, a U.K. newspaper reported.

Releasing the bank details of 2,000 "high net worth individuals" and companies could reveal huge potential tax evasion, The Observer reported on Sunday.

Both American and British firms and individuals, including about "40 politicians," will be implicated, Rudolf Elmer, a former employee of Swiss-based Bank Julius Baer, told the newspaper.

The list of individuals and companies includes multinational conglomerates and hedge funds that are "using secrecy as a screen to hide behind in order to avoided paying tax," Elmer told the Observer.

U.S. authorities are currently trying to build a legal case against WikiLeaks and some of its collaborators, claiming the release of the files puts lives at risk.
