Egypt’s Muslim Brotherhood-led parliament began drawing up a no-confidence motion against the military-appointed government Thursday, further escalating the Islamists’ increasingly public power struggle with the country’s ruling generals. The Islamists were also squabbling with liberal and secular groups over the commission that is to draw up the nation’s new constitution. After the Brotherhood took a clear majority on the 100-member body for itself, 25 other members resigned. The latest was the representative of Al-Azhar, the pre-eminent institute of Islamic learning in the Sunni Muslim world.
