CAIRO - Egypt's Islamist president has given the army temporary power to arrest civilians to help secure a constitutional referendum seen by the Muslim Brotherhood as a triumph for democracy and by its liberal foes as a religious straitjacket.
President Mohamed Morsi, bruised by the political uproar in which protesters have besieged his graffiti-besmirched palace to demand his downfall, has rescinded a November 22 decree giving him wide powers, but has not budged on the referendum date.
A decree issued by Morsi late on Sunday means the armed forces can arrest civilians and refer them to prosecutors until the results of the referendum are announced.
Despite its limited nature, the edict will revive memories of Hosni Mubarak's emergency law, also introduced as a temporary expedient, under which military or state security courts tried thousands of political dissidents and Islamist militants.
A cabinet source said ministers had reviewed the decree last week, saying troops had secured elections during a military-run transition after Mubarak but, with a civilian president in charge, now needed a decree to allow them to play that role.
Protests and violence have racked Egypt since Morsi decreed himself extraordinary powers he said were needed to speed up a troubled transition since Mubarak's fall 22 months ago.
Whatever the outcome of Saturday's referendum, the crisis has polarised Egypt and presages more instability at a time when Morsi needs to enact tough policies to steady a fragile economy.
With the political crisis heating the streets, Morsi suspended tax increases on Monday, only hours after the measures had been officially enacted, casting doubts on the government's ability to push through tough economic reforms that form part of a proposed $4.8 billion IMF loan agreement."Violent confrontation brewing"
Islamists and their opponents are planning rival rallies in different parts of Cairo before the vote set for Saturday.
Rejecting the referendum, opposition groups have called for mass protests on Tuesday, saying Morsi's eagerness to push the constitution through could lead to "violent confrontation".
Islamists have urged their followers to turn out "in millions" the same day in a show of support for the president and for a referendum they feel sure of winning with their loyal base and perhaps with the votes of Egyptians weary of turmoil.
The opposition National Salvation Front, led by liberals such as Mohamed ElBaradei and Amr Moussa, as well as leftist firebrand Hamdeen Sabahy, has yet to call directly for a boycott of the referendum or to urge their supporters to vote "no".
Instead it is contesting the legitimacy of the vote and of the whole process by which the constitution was drafted in an Islamist-led assembly from which their representatives withdrew.
The opposition says the document fails to embrace the diversity of 83 million Egyptians, a tenth of whom are Christians, and invites Muslim clerics to influence lawmaking.
But debate over the details has largely given way to noisy street protests and megaphone politics, keeping Egypt off balance and ill-equipped to deal with a looming economic crisis.
"Inevitability of referendum deepens divisions," was the headline in Al-Gomhuriya newspaper on Monday. Al Ahram
daily wrote: "Political forces split over referendum and new decree."
Morsi issued another decree on Saturday to supersede his November 22 measure putting his own decisions beyond legal challenge until a new constitution and parliament are in place.
While he gave up extra powers as a sop to his opponents, the decisions already taken under them, such as the dismissal of a prosecutor-general appointed by Mubarak, remain intact."Unwelcome" choice ahead
Lamia Kamel, a spokeswoman for former Arab League chief Moussa, said the opposition factions were still discussing whether to boycott the referendum or call for a "no" vote.
"Both paths are unwelcome because they really don't want the referendum at all," she said, but predicted a clearer opposition line if the plebiscite went ahead as planned.
A spokeswoman for ElBaradei, former head of the UN nuclear watchdog, said: "We do not acknowledge the referendum. The aim is to change the decision and postpone it."
Mahmoud Ghozlan, the Muslim Brotherhood's spokesman, said the opposition could stage protests, but should keep the peace.
"They are free to boycott, participate or say no, they can do what they want. The important thing is that it remains in the peaceful context to preserve the country's safety and security."
The army stepped into the conflict on Saturday, telling all sides to resolve their disputes via dialogue and warning that it would not allow Egypt to enter a "dark tunnel".
A military source said the declaration read on state media did not herald a move by the army to retake control of Egypt, which it relinquished in June after managing the transition from Mubarak's 30 years of military-backed one-man rule.
The draft constitution sets up a national defense council, in which generals will form a majority, and gives civilians some scrutiny over the army - although not enough for critics.
In August Morsi stripped the generals of sweeping powers they had grabbed when he was elected two months earlier, but has since repeatedly paid tribute to the military in public.
So far the army and police have taken a relatively passive role in the protests roiling the most populous Arab nation.
The elite Republican Guard has yet to use force to keep protesters away from the presidential palace, where clashes with Islamists killed seven people and wounded 350 last week.
The Muslim Brotherhood has voiced anger at the Interior Ministry's failure to prevent protesters setting fire to its headquarters in Cairo and 28 of its offices elsewhere.
