A government-chosen panel of physicians reported that Mubarak’s heart condition put him at risk of a sudden attack. The 83-year-old former leader suffers from atrial fibrillation and depression, making him unfit for transfer to prison.

The medical report, ordered by the prosecutor general and made public on Tuesday, says Mubarak is too weak to get out of bed without help.

Last week, Mubarak was ordered to stand trial for alleged complicity in the government-sponsored violence during Egypt’s revolution. The former ruler has been in custody at a hospital in the Red Sea resort of Sharm el-Sheik since April.
