Wikileaks given data on Swiss bank accounts
The data - which is not yet available on the Wikileaks website -
d&g online store was held on two discs handed over by Rudolf Elmer at a press conference in London.
Mr Assange promised full disclosure once the information had been vetted.
Mr Elmer
d&g sunglasses is scheduled to go on trial in Switzerland on Wednesday for breaking bank secrecy laws.
The banker, who has given data to Wikileaks before,
d&g handbags was fired from Swiss bank Julius Baer in 2002.
According to a report in Swiss newspaper Der Sonntag, the data covers multinationals, financial firms and wealthy individuals from many countries, including the UK, US and Germany, and covers the period 1990-2009.

"Once we have looked at the data... there will be full revelation," said Mr Assange,
d&g outlet who is currently on bail and confined to the UK due to an extradition request from Sweden.
He said the data would be vetted but that it was difficult to say how long this would take. The vetting would depend on the volume of information and how it was delegated, Mr Assange said, although he suggested it could be as little as two weeks.
Other groups - such as the Tax Justice Network or financial media outlets - might be asked to help in the vetting process, he added.
Mr Assange also said some information was likely to be handed over to the authorities - mentioning specifically the UK's Serious Fraud Office - as was the case with a previous leak concerning Icelandic banks.
Although it was not confirmed what activities might be covered by the data, the Wikileaks head noted that previous data from Julius Baer provided by Mr Elmer had shed light on tax evasion, the hiding of proceeds of criminal acts and "the protection of assets of those about to fall out of political favour".
