Ukrainian Deputy Foreign Minister Olena Zerkal has tendered her resignation. She posted her resignation letter on Facebook.
"I tender my resignation as deputy foreign minister of Ukraine for European integration," she said.
Zerkal noted that she was stepping down as deputy foreign minister but will remain a diplomat and a concerned citizen.
She thanked the people she had worked with for the past five years and a half, saying that over this time the team had not been given instructions or forced to work, while any achievements were thanks to people concerned.
In May 2019, ex-President Petro Poroshenko put Zerkal in charge of Ukraine's delegation to the International Tribunal of the Law of the Sea hearing the case of the Russian seizure of three Ukrainian naval ships and 24 crew members.
Zerkal first said that she was going to resign in August. Recently, she quoted disagreements with the current authorities' foreign policy course as a reason to step down.
Ukraine's ambassador to the Netherlands, Vsevolod Chentsov, is expected to replace Zerkal in international courts.
