The death of ex-spy chief Omar Suleiman was primarily caused by psychological distress not ill physical conditions, said Suleiman’s head manager Hussein Kamal.

Kamal suggested in a television appearance that Suleiman suffered from ill psychological conditions due to Egypt's deteriorating state, where he was unable to eat and lost 10 kilos.

Suleiman's aide insisted that the former intelligence chief was a fighter who could not tolerate anything short of success, pointing that he was aware of people's appreciation for him as shown in gaining citizen endorsements during the presidential elections, the Middle East News Agency.

He confirmed that there was a failed attempt to assassinate Suleiman during the January 25 uprising that toppled Mubarak’s 30-year rule, adding that whoever is responsible remains anonymous.

Kamal revealed that the Egyptian intelligence was aware, prior January 25, 2011, that an uprising was approaching, where Suleiman offered solutions to avoid its breaking out in a ministerial meeting. He added that the intelligence's role is to provide information, not take action.

Suleiman, who died on Thursday, served as Mubarak's vice-president during the 18 days of rage that toppled the regime.
