"We have been claiming for a year that all the benefits of the derogation are for Lukoil and the Putin regime and that the Bulgarian consumer has no benefit from it," GERB MP Delyan Dobrev said, commenting published information that Russian company Lukoil took advantage of sanction loopholes to earn €1 billion for the Kremlin's military needs.

He announced that he was preparing a new proposal for the immediate termination of the derogation, which would be submitted to the National Assembly. The idea was supported by the chairman of the parliamentary group of the Movement for Rights and Freedoms, Delyan Peevski. "We think this thing must happen immediately. The parties that do not support it are pro-Putin parties," Peevski said.
