The American Embassy in Cairo helped a young [activist"] attend a US-sponsored summit for activists in New York. On his return to Cairo in December 2008, [he] told US diplomats that an alliance of opposition groups had drawn up a plan to overthrow President Hosni Mubarak and install a democratic government in 2011. The disclosures, contained in previously secret US diplomatic dispatches released by the WikiLeaks website, show American officials pressed the Egyptian government to release other dissidents who had been detained by the police. In a secret diplomatic dispatch, sent on December 30 2008, Margaret Scobey, the US Ambassador to Cairo, recorded that opposition groups had allegedly drawn up secret plans for "regime change" to take place before elections, scheduled for September this year. The memo, which Ambassador Scobey sent to the US Secretary of State in Washington DC, was marked "confidential" and headed: "April 6 activist on his US visit and regime change in Egypt." It said the activist claimed "several opposition forces" had "agreed to support an unwritten plan for a transition to a parliamentary democracy, involving a weakened presidency and an empowered prime minister and parliament, before the scheduled 2011 presidential elections".
