Egypt has been mulling over revoking the Egyptian citizenship granted to President Recep Tayyip Erdoğan‘s son Bilal during the term of former President Mohammed Morsi, and a court case concerning the matter continues, in the latest step of rancor that could bring bilateral relations between the two countries to a new low.

The case concerning the possible revocation of Bilal Erdoğan‘s citizenship has been postponed to October, according to Egyptian media.

According to the claims in the Egyptian al-Masry al-Youm daily on Sunday, Morsi, who was ousted from office in a military coup in June 2013, had given Bilal Erdoğan Egyptian citizenship on April 13, 2013, two months prior to the military intervention. Now the case being overseen by the Egyptian Supreme Court over whether to revoke the citizenship of Bilal, among others, has been postponed until October.

The report also claimed that Bilal had used the Egyptian passport issued to him by the previous administration to flee to Georgia after a huge corruption scandal went public on Dec. 17, 2013. The graft investigation, the largest of its kind in Turkey’s history, incriminated four former Cabinet ministers, their families, prominent businesspeople and several members of then-Prime Minister Erdoğan’s family on charges of bribery and transferring gold to Iran in order to undermine US-led sanctions.

According to al-Masry al-Youm, Egyptian citizenship was also granted not only to Bilal Erdoğan but also to several other Turks deemed close to the Hamas administration in Palestine and by extension to the Muslim Brotherhood administration in Egypt. Morsi was sentenced to death in May, nearly three years after he became Egypt’s first freely elected president, on charges arising from the killing of protesters during demonstrations in 2012.

Bilal Erdoğan claims al-Masry al-Youm report work of ‘parallel structure’

The Foundation of Youth and Education in Turkey (TÜRGEV) denied the allegations on Monday, calling them “slander and lies” and continued by claiming the reports were a part of a “character assassination.” It also stated that Bilal Erdoğan is not an Egyptian citizen and did not use an Egyptian passport to flee to Georgia.

Bilal Erdoğan also claimed that the report in al-Masry al-Youm was the doing of the “parallel structure,” a term invented by his father to vilify the faith-based Gülen movement, also known as the Hizmet movement. “I will not flee the country I was born in and worked for due to the lies of a network of espionage and treason concealed as a movement [referring to the Hizmet movement], or [one of] their hired gun newspapers,” Bilal was quoted as saying.

Erdoğan and the AK Party government have launched a self-declared war against the Hizmet movement, inspired by the ideas of Turkish Islamic scholar Fethullah Gülen, after a corruption probe went public on Dec. 17, 2013, incriminating senior members of the government, the sons of three former ministers and government-affiliated figures as well as family members of then-Prime Minister Erdoğan.

Bilal’s name has been in the spotlight ever since a voice recording surfaced allegedly featuring the voice of then-Prime Minister Erdoğan ordering Bilal to dispose of vast amounts of cash — reportedly as much as $1 billion — during the corruption operation which went public on Dec. 17, 2013. During five wiretapped phone conversations, a voice alleged to be that of Erdoğan is heard telling his son to dispose of large sums of money hidden in several relatives’ homes on the day police raided a number of locations as part of the operation.

Towards the end of the recordings, Bilal Erdoğan tells his father that he and others have “finished the tasks you gave us,” implying that the whole sum was “zeroed.”

Bilal also made headlines more recently when the BMZ Group, a company owned by Bilal and other family members, purchased a tanker at a cost of $18 million. The tanker, given the name “Poet Qabil,” is the fourth acquired by the BMZ group.
