Julian Assange is not one to lie low.
The Wikileaks founder on Monday held a press conference in London at which ex-banker Rudolf Elmer handed him two CDs containing details of more than 2000 Swiss bank accounts.
Mr Elmer, a former executive at Swiss private banking group Julius Bär, alleges the disks contain proof that 40 politicians, and a bevy of multinational companies, are guilty of tax evasion.
Mr Assange told media at the Frontline Club gathering that "He [Elmer] is clearly a bona fide whistleblower... We have some kind of duty to support him in that matter."
However, Wikileaks will seek to verify information contained on the disks before making any of it public.
Mr Elmer worked for Julius Bär for eight years in the Caymen Islands - a tax haven - before being dismissed from his COO role in 2002.
In 2007, he became one of the first whistleblowers to supply Wikileaks, handing the site client data in 2007.
On Wednesday, Mr Elder faces trial in Switzerland on charges stemming from the 2007 handover.
Mr Assange is currently on bail pending an extradition hearing. Swedish authorities want to question the Wikileaks founder in relation to sex charges.
Bank of America prepares for Wikileaks attack
Separately, the Bank of America has today denied that an outage on Saturday NZ time was the result of an attack by Wikileaks supporters.
The online banking glitch was the result of a "routine systems outage," the bank told media.
Before Christmas, Wikileaks said it had obtained revealing documents about the bank, which responded, in part, but buying "dirty URLs" that could be used against its chief executive, Brian Moynihan, including BrianMoynihanBlows.com, BrianMoynihanSucks.com, BrianTMoynihanBlows.com, and BrianTMoynihanSucks.com.
The tactic mirrors BP's effort to buy key Google search words, including "oil spill" during its Gulf of Mexico crisis last year.
