Poland’s prime minister, Mateusz Morawiecki, welcomed the country’s constitutional court’s rejection of the supremacy of European Union law over member-states’ national legislation. The European Commission quickly disagreed with the court, saying the ruling raised “serious concerns”. Mr Morawiecki’s right-wing populist Law and Justice party has been accused by the EU of politicising the judicial branch and undermining the rule of law.
