CAIRO – Faced with an unprecedented strike by the courts and massive opposition protests, Egypt's Islamist president is not backing down in the showdown over decrees granting him near-absolute powers.

Activists warn that his actions threaten a "second revolution," but Mohammed Morsi faces a different situation than his ousted predecessor, Hosni Mubarak: He was democratically elected and enjoys the support of the nation's most powerful political movement.

Already, Morsi is rushing the work of an Islamist-dominated constitutional assembly at the heart of the power struggle, with a draft of the charter expected as early as Thursday, despite a walkout by liberal and Christian members that has raised questions about the panel's legitimacy.
