The European Parliament took a shift to the right after a four-day election concluded on Sunday, with more eurosceptic nationalists and fewer mainstream liberals and Greens. The parliament's most important role is reviewing and approving new legislation and it generally comes up with amendments on which it and EU governments need to agree before EU regulations or directives can enter force. The EU assembly will also need to approve the next president of the European Commission - most likely incumbent Ursula von der Leyen for a second term - and their 26 other commissioners.
