The request of a ministry that then had to be proven in court. The court agreed. The court system that has been reformed according to EU standards.

So back to your original claim that it was "Zelensky did manage to ban another opposition party", do you still stand by that?

Considering you've provided no links to any opinion polls that show Zelenksy is unpopular, you are correct, there is nothing to see. Feel free to justify your opinion anytime you like.
