As Ukrainian troops gained ground in eastern Ukraine in early July, separatist leader, Aleksander Borodai, a Russian national, left for Moscow for political consultations.

After what he described as successful talks with unnamed people there, he returned to the rebel stronghold of Donetsk to introduce a new senior figure in his self-proclaimed republic, a compatriot seasoned in the pro-Russian separatist movement in Moldova and a war between Russia and Georgia.

Vladimir Antyufeyev was named "deputy prime minister" by Borodai on July 10, one of several native Russians to have taken charge of the separatist rebellion in Ukraine's eastern regions.
