KYIV, Sept 20 – Naftogaz Ukrayiny should be de-monopolized, and before this is done the company should not attempt to influence prices, Prime Minister Volodymyr Groysman has said, opening a government meeting in Kyiv on Wednesday.

"The monopolies always try to use their position to groundlessly increase price and increase expenses. I would not allow that any monopoly groundlessly even approached the revision of gas prices in our country," he said.
