"Consultations on the new Special Representative of the OSCE Chairman in Ukraine are held at the moment," Saule Mukhametrakhimova told RIA Novosti.
Earlier in the day, a source close to negotiations stated that Tagliavini resigned over disagreements between the sides involved in Contact Group talks on Ukrainian reconciliation.
On Tuesday, closed door meetings of the working groups of the trilateral Contact Group on Ukraine began in Minsk, Belarus. The source said some of their participants "extremely upset" Tagliavini with nonconstructive behavior and low negotiability.
In June 2014, Tagliavini was appointed as an OSCE representative at the talks. She was also among the signatories of the February Minsk peace agreements, stipulating a ceasefire, heavy weaponry withdrawal and prisoner exchanges.
