(Reuters) – The Slovak Finance Minister Igor Matovic stated Tuesday that he will propose a tax on Russian crude oil processed in Slovakia. This clashes with a coalition partner of the government as he seeks more revenue to support anti-inflationary measures.

This proposal was made as European Union countries seek to agree on tougher sanctions for Russia’s invasion of Ukraine. This includes an oil embargo, from which Slovakia sought temporary relief.

The Russian oil that Slovakia imports from Russia via the Soviet-era Druzhba pipeline (Friendship), is what it relies upon. Slovnaft operates the country’s single refinery. It is owned by Hungary’s MOL.

Matovic claimed that the extra revenue from the state’s special tax could amount to around 300million euros ($316.29million) and could help cover the cost of some state-sponsored measures to lower the rising costs of inflation.

According to him, the 30% tax should be taken from the difference in crude oil prices from Russia and those from other suppliers.

Matovic stated that he expects to receive sufficient support when he presents the proposal to the government Wednesday. However, it is uncertain and has been criticised by one of his coalition partners.

Economy Minister Richard Sulik of the SaS party, which has been against higher taxes, stated that the plan could result in higher fuel prices and he threatened to veto it, TASR news agency reported.

As it sought ways to assist households with spiraling energy bills, the government proposed a tax on excess profits from nuclear power plant.

After reaching an agreement to limit household electricity prices with Slovenske Elektrarne (which operates two of the country’s nuclear plants), it dropped that tax. Enel (BIT:), and Czech billionaire Daniel Kretinsky’s EPH group.
