Iceland's leader Sigmundur Gunnlaugsson quit on Tuesday. His name was in the 11.5 million leaked documents from a Panama law company. They have information about the world's rich and powerful people not paying tax. They include many present and past world leaders. The company is called Mossack Fonseca.
Many people are now worried. The new FIFA president is in the documents. Newspapers say Mossack Fonseca also worked with people who many countries disliked. One was a cousin of Syria's leader. Newspapers also say it worked with companies in North Korea. There is up to $32 trillion in untaxed money.
