The retrial of deposed Egyptian President Hosni Mubarak on corruption and conspiracy charges is due to open in the capital, Cairo.
Mubarak was convicted last June of conspiring to kill protesters during the 2011 revolt that ended his rule.
But a retrial was ordered in January after a court accepted his appeal against his life sentence, citing procedural irregularities.
About 850 people were killed in the 2011 crackdown.
Mubarak, 84, is in poor health and currently being held in a military hospital in Cairo.
As at his first trial, which lasted 10 months, he was carried into the the courtroom at Cairo's police academy on Saturday on a stretcher.
He was flown by helicopter on Saturday to the courthouse on the outskirts of Cairo. State TV showed him being wheeled into the building on a stretcher, wearing a white tracksuit.
DisappointedTwo sons of the former leader and a former interior minister, Habib al-Adly will also be re-tried, facing the same charges as before.
Al-Adly was sentenced to life last year for contributing to the killing of protesters, and for five and 12 years for corruption charges.
Mubarak's sons, Gamal and Alaa, will be retried on corruption charges for which they were acquitted in June, because of the expiry of a statute of limitations.
The former president was also found not guilty of corruption.
The 2011 uprising ended Mubarak's 29-year rule of Egypt.
Families of protesters who died in the crackdown were disappointed that the former president was not convicted of ordering the killings.
There was also been anger among some that he has not faced trial for abuses allegedly committed earlier in his rule.
But the BBC's Alem Maqbool says news of the retrial has been overshadowed by the political instability and insecurity which followed the revolution.
