Here is what wikipedia says: The Isle of Man case is the incident in which Kemal Kılıçdaroğlu, the leader of the Republican People's Party, claimed during his party's group meeting in the Turkish Grand National Assembly on December 21, 2017, that President Recep Tayyip Erdoğan's relatives evaded taxes by transferring money to a company in the Isle of Man, and both parties subsequently took the matter to court.[1] The issue has become a hot topic in Turkey and has been a topic of discussion by many politicians. Although multiple lawsuits have been filed regarding the claim, there has been no court decision confirming the claims as a result of the lawsuits filed. However, in 2022, the court overturned the compensation decisions against Kılıçdaroğlu.[2] This situation was interpreted as the Supreme Court of Appeals confirming the Isle of Man claim.[3] https://tr.wikipedia.org/wiki/Man_Adas%C4%B1_davas%C4%B1
