"The United States diplomatic cables leak, widely known as Cablegate, began in February 2010 when WikiLeaks—a non-profit organization that publishes submissions from anonymous whistleblowers—began releasing classified cables that had been sent to the U.S. State Department by 274 of its consulates, embassies, and diplomatic missions around the world."

Summary of interesting facts about Singapore from Wikileaks. "Deliberate lack of transparency in Temasek Holdings", "Govt does not want more Singaporeans to have degrees", "Lack of independence of Singapore judiciary in political cases", "Sustainablility of Singapore economic model", "Singapore's uncaring elite", "Frustration among Singapore journalists over govt control"
