US-convicted banker quits as Istanbul exchange chief
A top Turkish banker convicted in the US of busting sanctions on Iran resigned on Monday as the chief executive of the Istanbul stock exchange, state media reported.
Atilla was released from jail in the US in 2019 after spending two years behind bars, and was named head of the stock exchange in October 2019.
Atilla resigned "of his own accord", the Borsa Istanbul exchange said in a statement, quoted by state news agency Anadolu.
A US federal court is expected to put Halkbank on trial later this year after charging it with six counts of fraud, money laundering and sanctions offences in 2019.
Turkish President Recep Tayyip Erdogan has dismissed the claims, insisting the case against Atilla was "politically motivated".
Relations between the two NATO allies remain strained over the Halkbank dispute, Syria and other international issues.
Turkey's sovereign wealth fund, which owns Borsa Istanbul, is reportedly planning an initial public offering of the exchange operator next year.
