A deputy head of the presidential administration in charge of foreign policy, Kostyantyn Yeliseyev, has resigned.
"We make space for a new team," the Yevropeyska Pravda website quoted him as saying.
Yeliseyev confirmed that he had indeed tendered his resignation and said that he was ready to help his successor by providing advice and outlining priorities in his role.
"I am a supporter of this European tradition that when a new team comes, we do not cling to seats and quietly do a handover, all the files have been prepared. I am even ready to put priorities that require attention on the table for my successor whom I, unfortunately, do not know yet," he said.
Yeliseyev was appointed a deputy head of the presidential administration on 15 July 2015. Previously, he had headed Ukraine's Representative Office to the EU for five years.
Another deputy head of the presidential administration, Oleksiy Filatov, resigned last week.
