WikiLeaks will sue Visa and MasterCard for their refusal to process donations to the website. The whistle-blower service is now working with the lawyers in Denmark and Iceland along with its credit card processing partner DataCell to launch a lawsuit against the card schemes for "engaging in an unlawful, US influenced, financial blockade".

The lawyers for WikiLeaks say that in case the blockade is not removed Visa, MasterCard and Danish card processor Teller will be litigated in Denmark and a request for prosecution under EU competition laws will be filed with the European Commission.
