CAIRO (Reuters) - Egypt's parliament sits for the first time Monday since Hosni Mubarak was deposed after a historic election that put Islamists, repressed under the former president, in the driving seat.
The Muslim Brotherhood's party was the biggest winner in the first free vote in decades. It has vowed to guide Egypt in the transition to civilian rule after generals took charge after Mubarak was pushed out of office in February.
The rise of the Islamists marks a sea change from Mubarak's era when parliament was a compliant body stuffed with members of his National Democratic Party and the Muslim Brotherhood was officially banned though semi-tolerated.
Generals will remain in charge until after a presidential election in June when they have promised to handover power, although many Egyptians suspect the army may seek to cling on to power from behind the scenes even after that.
"It will be a historical session in Egypt's transition to democracy and civilian rule," Mohamed Beltagy, a leading member of the Brotherhood's Freedom and Justice Party (FJP), said before the first session, due to begin at 11 a.m. (0900 GMT).
One of the first steps in Monday's session will be electing the speaker, set to be the FJP's nominee, Mohamed el-Katatni.
Youth movements, who put national pride before religion when they galvanised Egyptians in the 18-day revolt against Mubarak, said they would demonstrate outside the assembly to ensure protesters killed in the uprising were not forgotten.
"We do not contest the popular mandate of parliament, but it better deliver on the rights of martyrs and wounded. We fear political parties may vie for political gain and ignore the youth," activist Mohamed Fahmy said.
Liberals were pushed into third place behind the FJP and ultraconservative Islamist Salafis led by al-Nour party, the surprise runners up. The FJP says it controls almost half the 498 elected seats, with a few re-runs still to be held.
Although Islamists dominate, it is unclear whether they will form a single bloc in parliament, which will have a key role in drafting the new constitution. The Brotherhood has said it wants to be inclusive and ensure all voices in Egypt are heard.
Monday's session marks the revival of an assembly that in the early 20th century was a vibrant forum for the nation's aspirations and filled with deputies who vied with the monarch and Egypt's British overlords.
Parliament's independent voice was extinguished after a 1952 coup that toppled the king and swept military-backed autocrats to power. Mubarak was a former air force commander and the ruling military council is now led by Mubarak's defense minister for 20 years, Mohamed Hussein Tantawi.
"The Egyptian military seems at this point determined to carve out an exception to democratic rule for its area of power and interest," Human Rights Watch's executive director Kenneth Roth said Sunday at the launch of the group's annual report in Cairo.
Parliamentarians see the new assembly as bringing Egypt a step closer to ending military rule.
"We say that we respect and appreciate the army but the military council must be held accountable for any mistakes ... No one is above accountability," the Brotherhood's general guide, Mohamed Badie, said last week.
But the Islamist group has also previously said it does not seek a confrontation with the military.
Some analysts have suggested the army will not fully abandon politics unless the Brotherhood and other prominent political parties offer guarantees that it will not face legal retribution over the killing of protesters.
Mubarak, 83, is now on trial for his role in the deaths of 850 people during the uprising. Scores of people have been killed in sporadic eruptions of violence since then, including demonstrations against army rule in November and December.
Several youth groups say they will hold peaceful protests in front of parliament in central Cairo to ensure the new assembly supports those wounded or families of those killed in protests.
A Brotherhood source said its members would form a human chain around parliament to stop any protest turning violent.
