EU foreign ministries to discuss abolition of the unanimous decision-making principle today - RBC
The principle allows EU countries to veto the application of sanctions. For example, Hungary used its veto when the EU was working on restrictions on Russian oil in spring.
IF News: Eliminating the veto would allow the EU to pass sanctions by majority vote, which would speed up decision-making. At the same time, sanctions will become tougher for both sides, since there is no need to please every EU country.
