The military-backed transitional government stoked political tensions in late 2013 when General Abdel Fattah el-Sisi said the military should have immunity under the new constitution.
Early signs showed that the constitution, due to be voted on in a referendum in December, would strengthen the military's power and give it new powers to try civilians in military courts.
The transitional regime faces a series of close dead-lines that will enable it to hand over power to an elected government in 2014.
Parliamentary polls are set for February or March, then the presidential election is planned for mid-2014.
All signs suggest el-Sisi will run.
The government has arrested Muslim Brotherhood leaders and broken up their protests.
It said that the Brotherhood could participate in the constitution vote and the parliamentary poll, but the party's leaders have stressed that they would not take part in the referendum. ●
