Turkish Super Lig football club Galatasaray has reportedly opted to end a shirt sponsorship deal with Dumankaya following allegations that the construction company provided financial support to a political movement that is considered to be a terrorist organisation by the government.
According to various media reports in Turkey, Istanbul's Anatolian Side Public Prosecutor’s Office is in the process of investigating the firm’s alleged funding of the Gülenist Terror Organisation (FETÖ).
In October of last year, Dumankaya signed a three-season deal, from 2015-16 to 2017-18, to serve as Galatasaray’s main front-of-shirt sponsor. The agreement was set to be worth TRY30m (€9.4m/$10.4m) over the three-year term.
However, reports in the Turkish media suggest the team will not carry a logo on its shirt for its match against Bursaspor tomorrow (Friday).
