President Mohamed Morsi did not attend the wake.
The funeral march of Egypt's ex-spy chief Omar Suleiman had taken in Cairo on Saturday amid tight security and in the presence of several thousand mourners, including politicians and top military brass. Tantawi was among the marchers while Morsi sent a representative.

Suleiman was appointed in 1993 by then-president Mubarak as head of Egypt's intelligence service.
During his 18-year tenure, he was the regime's policy architect on many key political issues, including the Palestinian-Israeli conflict as well as relations with Nile Basin countries.
Suleiman, appointed as vice-president during the January uprising in 2011, announced Mubarak's decision to resign from the presidency on 11 February on national television.
