Further charges against Hosni Mubarak's sons Gamal and Alaa

The two sons of Hosni Mubarak, the deposed President, were charged with insider trading yesterday and are to be tried before a criminal court. They were among nine men who made illicit gains from the sale of a bank, according to a statement from the prosecutor-general's office which was reported by the state news agency. It gave no other details.

Mubarak and his sons, Gamal, who was once his presumed heir, and Alaa, a wealthy businessman, are already on trial on charges of corruption. A verdict is expected on 2 June.

The deposed President faces additional charges of complicity in the deaths of some 900 protesters during the uprising last year. If convicted, he could be sentenced to death. Mubarak stepped down in February 2011, and was arrested with his sons two months later.

The prosecutor's statement said Gamal unlawfully made a profit of nearly 500m Egyptian pounds (£53m) from the sale of the Watani Bank and that Alaa used insider information about the bank to reap an illegal profit of some 12m Egyptian pounds.

One of the other men charged is the son of Mohammed Hassanein Heikal, Egypt's best-known political writer and a longtime confidante of the late leader Gamal Abdel-Nasser.

A date for the trial has yet to be announced and the seven other people charged in the case have been released on bail but are banned from leaving the country.
