President Mursi set to press ahead with talks Cairo's Tahrir square woke to a quiet Saturday morning on a day President Mursi is expected to push ahead with talks on ways to find an end to the crisis. Egypt's main opposition leaders have vowed to boycott the discussions. Demonstrators turned their anger towards an administrative complex in the square erecting barbed wire to prevent employees getting to work. We have started to escalate our approach. Just as the Supreme constitutional court was closed, the judges work was suspended by the brotherhood and Mursi didn't do anything about it, so we had to escalate our approach. We are not against the employees here, we are against a presidential decision that is not sound," explained one of the demonstrators. It's been reported in Egypt's state-run newspaper that the president is set to authorise the army to help police keep order and would be given powers of arrest. There was no indication as to when the measures aimed at, "protecting vital institutions" would come into force. Overnight tens of thousands of protesters gathered near the presidential palace. Opposition leaders say the president has offered no concession on his decisions to expand his powers and to put a new draft constitution to a referendum. A top official said the president could conditionally postpone the vote. More about: Cairo, Egypt, Egyptian army, Egyptian politics, Protests in Egypt
