The lawyer of ousted president Hosni Mubarak, Farid El-Deeb, has claimed his client is still legally the Egyptian president.

Under article 78 of the constitution, said El-Deeb in court on Sunday, the president remains in office until a successor is installed.

El-Deeb also claimed that Mubarak’s resignation was void because it took place via a telephone call to Omar Soliman, the former vice president, and was not put in written form.

The trial has been adjourned until Monday.
