Egypt's Hosni Mubarak will apologize to the nation and plead for amnesty, the Muslim Brotherhood has said in a report published in its site, even as prosecutors tightened the noose around the 82-year old former dictator and his family.

The Brotherhood, which is one of the largest opposition forces that successfully brought the dictator's three-decade rule to an end, did not give further details.

The deposed president had been arrested in his hospital bed last month as prosecutors pressed ahead with investigations into his alleged financial wrong-doings while in office. His two sons too had been arrested and sent into a 15-day custody.

On Friday, his wife reportedly relinquished some of the family's assets as Egypt's anti-corruption investigation turned the heat on the former first family.

The Washington Post reported that Suzanne Mubarak gave authorities the power of attorney to withdraw up to $3.4 million from two bank accounts.

It is believed that the Mubarak family could have stashed away billions of dollars of corruption money it amassed in three decades of power.

The disgraced leader is also facing criminal charges related to the death of protesters during the pro-democracy campaign that unseated him early this year.

There were reports that he could be given the death penalty if convicted of ordering the killing of anti-government protesters during the popular uprising.

“Certainly, if convicted for killing protesters, it could result in the death sentence,” Egypt's new Justice Minister Mohammed el-Guindi told Al-Ahram daily on May 2.
