The Parliamentary Investigation Committee presented a report on Friday in Parliament on the failed July 15 coup attempt, which blames Gülen for carrying out a secretive decades-old campaign to overthrow Turkey's democratically elected government and seize power in the country.

The head of the parliamentary committee, Reşat Petek, said that there is no doubt that the Gülenist Terror Group (FETÖ) led by U.S.-based Fetullah Gülen was behind last year's failed military coup, calling Gülen a "fraudster" who had been preparing for a takeover for the past 50 years.

Petek told reporters the report reveals that Gülen's movement "was behind the July 15 event with clarity and certainty," after evaluating all evidence and documents.

Gülen has "committed forgery numerous times, but he never went through an investigation. He attained his green [Turkish] passport with fake documents he collected," Petek said, adding that "documents and evidences collected by our commission confirm that."

MIT restructuring

The committee chairman also pointed out the lack of intelligence prior to the attempt.

He said the fact that there was no advance information about the coup bid proves "without a doubt…an intelligence failure".

Petek said a soldier from the army's aviation regiment played a key role in informing the chief of the National Intelligence Agency (MIT) on July 15, 2016, and termed it as a big factor in forcing the coup plotters to pull the time of the coup forward to 8 p.m. local time (1700 GMT), July 15, 2016, instead of 3 a.m. (0000 GMT), July 16, 2016.

The draft report called for the careful examination of reasons "why the National Intelligence Agency (MIT) was incompetent and lacked prior information about any coup attempt in Turkey's history of democracy".

It also called for restructuring of the MIT and cited the example of the Federal Bureau of Investigation (FBI) that witnessed a massive overhaul following the 9/11 attacks in the U.S.

It urged the MIT to scrutinize the personnel working at state institutions, particularly those employed at the Presidency, Prime Ministry, Turkish Armed Forces, Justice Ministry and the Directorate General of Security (police). It added that FETÖ members targeted the country's intelligence bureaus first during their infiltration efforts.

MIT cites lack of cooperation with military in own report

Petek also acknowledged some facts from the MIT report previously presented to the committee. The report said the intelligence agency had anticipated FETÖ's objective to conduct a coup attempt but was unable to gather intelligence on the date due to its inability to collect information from the Turkish Armed Forces (TSK) at the time.

The 36-page MIT report provided in-depth information on the FETÖ structure and detailed the MIT's efforts taken against the terror group while laying out the measures taken following the coup attempt. The critical report also included FETÖ's structure both domestically and internationally with detailed illustrations. Domestically, the MIT report laid out Turkey in five regions and defined Istanbul, Izmir, Ankara, Gaziantep and Erzurum as the cities "in charge."

Furthermore, the report said, "As the National Intelligence Agency informed the government's other institutions on the possibility that FETÖ would attempt a coup, intelligence on the specific date of the coup attempt was not found prior due to the inability to obtained intelligence from the TSK structure." The MIT's report also drew attention to FETÖ's potential threat to the country's national and international security, as it noted, "Following the coup attempt, both technical and physical security measures have been enhanced in all public organizations and institutions, while expediting the process of gathering the necessary requirements in defense and security in possible attacks and sabotage."

FETÖ's political ties

Petek, who is a member of parliament of the ruling Justice and Development Party (AK Party) from southwestern Burdur province, also said FETÖ builds ties with any stakeholder that is in power at a given time and is not bound to a single party, but rather it infiltrates the political set up.

"We have arrived at the conclusion that this is not an organization that communicates with just a single political party while keeping other parties at bay.

"Time to time, whether it is the ruling party or coalition parties, this organization finds out a way to use political parties to infiltrate the state's higher institutions, including the judiciary, military and the civil service," he said.

As an example of Gülen's affiliation with all political parties, Petek also showed a photocopied document of an alleged 1965-dated donation receipt by Gülen to the main opposition Republican People's Party (CHP), which accuses the government of cooperating with Gülenists until 2012.

In a press conference, CHP Deputy Aykut Erdoğdu vehemently denied Petek's claim, stating the receipt was a forged document and they will press charges against the claim.Cheating in exams

The draft report also focused on the fact that answers of the civil service recruitment exam -- known as the KPSS -- in 2010 had been leaked to FETÖ members in advance that allowed them to eventually infiltrate state institutions.

"To thwart FETÖ from manipulating public institutions exam ever again, recruitment should be based on merit and competence, and exams and promotions should be monitored carefully, based on open competition," the report said.

It said that cheating in the exams had allowed ideological, political and religious organizations to form their own groups within state bodies.

The report also called for clearing "militants" from all public institutions. So far, 2,236 educational institutions linked to FETÖ have been closed, it said.

FETÖ also "exploited" students who received education at their institutions and spread false information about Islam to those not familiar about the religion's true principles.

"The organization used people's religious faith to make false promises, eventually exploiting the dreams of younger generations and their future plans," it said.

FETÖ exists in 160 different countries, with around 800 schools and universities, 100 dormitories, close to 1,000 NGOs, associations and control over more than 200 media companies, it said.

"It is estimated that FETÖ's flow of capital is between $25-50 billion," it said, adding that there were around 3,000 high-ranking FETÖ officials.

The draft report also warned about the existence of "disguised" FETÖ members within the Turkish military that could "again quickly turn into an armed terrorist group".

"If FETÖ had succeeded in their bid on July 15, the Republic of Turkey would have seen its darkest, most chaotic period ever," it said.

"The night of July 15 was the biggest threat to the continuity of the state this country has ever seen," it added.

The draft report will be submitted to the parliamentary speaker in 15 days for approval.

The July 15 defeated coup left 250 people dead and around 2,200 injured.
