The American government secretly backed leading figures behind the Egyptian uprising who have been planning “regime change” for the past three years, The Daily Telegraph has learned. The American Embassy in Cairo helped a young dissident attend a US-sponsored summit for activists in New York, while working to keep his identity secret from Egyptian state police. On his return to Cairo in December 2008, the activist 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.
