Ashraf Marwan, the controversial son-in-law of Egypt's late President Gamal Abdel Nasser, has died, a state-run news agency reported Wednesday. He was 62.
The death of Marwan, suspected of being a double agent for Israel during the 1973 war, comes amid a controversy in Egypt about his role in the intelligence and business worlds.
The Middle East News Agency said initial indications suggested Marwan fell from his apartment balcony in the St James Park neighborhood in London. The MENA news agency said Scotland Yard was investigating.
Some opposition lawmakers recently demanded an investigation after Egyptian papers carried reports from Israeli media about Marwan's possible role as a double agent during the 1973 war, when Egypt and Syria waged a sneak attack against Israel on the Jewish holy day of Yom Kippur.
The Egyptian government has never commented on these allegations. MENA reported that Marwan received the highest honors for his "achievements" during the 1973 war from former President Anwar Sadat. The news agency did not elaborate.
Marwan's name first came up in "Myth Versus Reality: The Yom Kippur War - Failures and Lessons," a 2004 book by Eli Zeira, who was Israeli chief of military intelligence during the war.
Zeira indicated that Marwan was the agent who tipped Israel off about the start of the war, but Israel's leaders ignored the warning and were caught by surprise when Egypt and Syria attacked.
According to the Israeli media reports, Marwan first walked into the Israeli Embassy in London in 1969 and volunteered to give information but was turned down. He later was allegedly recruited by the Israeli intelligence agency, Mossad.
Born to a father who was a military officer in Nasser's presidential guard, Marwan joined the army himself after he finishing a degree in chemical engineering. He later worked as an assistant to Nasser and after Nasser's death in 1970, he became a political and security adviser to Sadat.
In the 1970s, Marwan worked as head of Egypt's huge government-owned military industry complex before he retired and moved to Britain 25 years ago to work in business.
