REYKJAVIK, Iceland – Iceland's coalition government collapsed Monday, leaving the country in political turmoil amid a financial crisis that has pummelled its economy and required an international bailout to keep the economy afloat.

Prime Minister Geir Haarde said he was unwilling to meet demands from his coalition partners in the Social Democratic Alliance, which insisted upon the post of prime minister in order to keep the coalition intact.

Haarde has been prime minister since 2006.

Foreign Minister Ingibjorg Gisladottir, who heads the Social Democrats, was expected to start talks with opposition parties in an attempt to form a new government. That government would sit until new elections are held, likely in May.

Haarde had previously said he wouldn't lead his Independence Party into new elections, because he has cancer.

He told reporters Monday that he had proposed Education Minister Thorgerdur Katrin Gunnarsdottir, of Haarde's own party, be appointed Iceland's new prime minister – but Gisladottir rejected that offer.

"It was an unreasonable demand for the smaller party to demand the premiership over the larger party," Haarde said.

Iceland has been mired in crisis since the collapse of the country's banks under the weight of debts amassed during years of rapid expansion. Inflation and unemployment have soared, and the currency, krona, has plummeted.

Haarde's government has nationalized banks and negotiated about $10 billion US in loans from the IMF and individual countries. In addition, Iceland faces a bill likely to run to billions of dollars to repay thousands of Europeans who held accounts with subsidiaries of collapsed Icelandic banks.

The country's commerce minister, Bjorgvin Sigurdsson, quit Sunday citing the pressures of the economic collapse. Sigurdsson, a member of Gisladottir's party, said Icelanders had lost trust in their political leadership.

Thousands have joined noisy daily protests in the last week over soaring unemployment and rising prices.
