The mastermind behind the assassination of Egyptian President Anwar Sadat in 1981, who has been released from prison since the fall of Hosni Mubarak regime, has plans to take part in post-Mubarak political future of Egypt, according to reports.

Islamic Jihad leader Abboud al-Zommor was the brain behind the killing of Sadat, who made peace with Israel and signed the Camp David peace treaty under the aegis of the United States. Al-Zommor was released last week after spending decades in Egyptian prison.

Now, after the ouster of former president Hosni Mubarak's government, al-Zommor plans to take part in mapping out the future of Egypt, the Doha-based Al Jazeera has reported.

The report said prisoners who have been released after the fall of the Mubarak regime are planning to form political movements. Thousands of people had been detained, most illegally, during the regime of Mubarak who strongly opposed the right wing Islamic groups in the country.

After the regime change, hundreds of illegal detainees have been released. Al-Zommor's 'Jihad' group was working for the overthrow of the secular government in the country and the establishment of an Islamic state, the report says.
