 There was a claim that Marwan was a "double-spy" who worked for Sadat and deceived the Israelis, but analysis of the evidence indicates Marwan's intelligence information was too destructive of Egyptian interests.Marwan was born in Egypt on 2 February 1944 to a respected family.His grandfather was the chief of the Sharia courts in Egypt, and his father, a military officer, reached the rank of General in the Egyptian Republican Guard.
