THE POWER OF SMALL EU MEMBER STATES AFTER BREXIT: HOW POWERFUL IS THE VISEGRAD GROUP?

The power of individual EU Member States has been changing over the past decades as a result of revisions to the voting systems and the enlargements of the European Union. The present article analyses the development of the voting power of individual Member States in the Council of the European Union before and after the withdrawal of the United Kingdom of Great Britain and Northern Ireland from the European Union. We use the calculation of the standardized Banzhaf power index to calculate the legislative power of the Member States. The calculations recorded in the table point to changes in the weights of national votes caused by Brexit. The article pays special attention to the Visegrad Group, which we define within the European Union as an informal group consisting of four Central European states - the Czech Republic, Hungary, Poland, and the Slovak Republic. The results indicate a significant growth of the voting power in Poland and more moderate growth in the other three Visegrad Group countries which contributes to the shift in the voting equilibrium within the ordinary legislative procedure of the European Union
