Iceland has long been angry at Britain's handling of the situation, which included the use of anti-terror legislation to seize the assets of Icelandic bank Landsbanki. A day later, Iceland took control of Kaupthing, the last of the three biggest commercial banks taken over as the north Atlantic island's financial system collapsed under the weight of tens of billions of dollars in foreign debts. "The Resolution Committee of Kaupthing has decided to sue the British Government and has the full support of the government," a press release from the Icelandic prime minister's office said.
