It has also been reported that the TFF have sacked several referees.

The TFF claimed that all members of its Committees have stepped down to help the investigation into United States-based cleric Fethullah Gulen, who the Government says was behind the coup that left more than 200 people dead.

Turkish armed forces unsuccessfully attempted to seize control of several key places in cities such as the capital Ankara and Istanbul.

They were unsuccessful after forces loyal to Turkish President Recep Tayyip Erdoğan maintained social order within 48 hours.

So far, more than 60,000 people in the military, judiciary, civil service, academia, media and other sectors have been either detained, suspended or placed under investigation over suspected links with Gulen who has denied orchestrating the coup.

Football's world governing body FIFA is yet to respond but the organisation has strict rules against Government interference in footballing matters.

The Committees that have been left unmanned are those for Arbitration, Discipline, Ethics, Licensing, Referees, Anti-Doping, Health and Foreign Relations.

The resignations come three weeks before the start of the new league season.

The coup in Turkey has affected sport in other ways - with the International Basketball Federation (FIBA) opting to cancel the Under-18 European Championship in northern city Samsun because of the crisis.

"The Committee took into consideration the current situation in Turkey and correspondence it has received by several National Federations, expressing their deep concerns about participating in the tournament, following apprehension from the parents of the players, who are still minors," a FIBA statement said.

The tournament will now be re-located and played at a later date.

Samsun did, however, host the start of World Deaf Championships, which went ahead as planned last month.
