According to the source, Gryzlov left the meeting because Marchuk began to discuss a topic not related to the Minsk agreements.

As stated by the representative of the self-proclaimed LC in the political subgroup Rodion Miroshnik, representatives of Kiev tried to impose a discussion of the incident in the Kerch Strait.

"Kiev representatives sought to impose a discussion of the incident in the Kerch Strait, which in no way relates to the range of issues discussed in the Minsk format," he said.

Earlier, Gryzlov commented on the appointment of Marchuk as a representative of Kiev in the contact group on the settlement of the situation in the Donbas.
