Delays in the implementation of the plan for unbundling of Naftogaz Ukrainy could lead to the suspension of financing by the European Bank for Reconstruction and Development (EBRD) used for gas purchases, Naftogaz Head Andriy Kobolev has said.

"Today we've received "a yellow card" from the EBRD - if the financial plan of Naftogaz is not approved by the end of July and the performance of the supervisory board is not adopted, then there could not be another tranche for gas purchases," he said at a round table entitled "The key role of Ukraine in the energy security of Europe" at the Verkhovna Rada.
