A dismissed Ukrainian official has accused former Georgian President Mikheil Saakashvili of defending the interests of a Turkish firm, the Hurriyet Daily News reports, citing Doğan News Agency.

Saakashvili, who is now serving as a new governor of Ukraine’s Odessa region, slammed Denis Antonyuk, then president of Ukraine’s state-owned airline operator, during a meeting of the country’s aviation authority on June 26, accusing him of corruption.

Ukrainian President Petro Poroshenko had announced Antonyuk would be dismissed, in a move that would only be formalized with a cabinet motion on July 1.

Doğan News Agency reported on July 8 Antonyuk had fired back by filing a criminal complaint against Saakashvili.

Writing to Ukrainian Chief Prosecutor Victor Shokin, Antonyuk said the former Georgian president had no legal right to attend the aviation authority’s meeting. Furthermore, he argued, Saakashvili defended the rights of a Turkish firm and oligarch Igor Kolomoysky’s Ukrainian International Airlines (MAU).

The report did not mention the name of the Turkish company. Largely in the construction sector, Turkish companies have scores of major investments in Ukraine worth more than $2 billion.
