Defiant Polish PM clashes with EU chief on bloc's laws

Polish Prime Minister Mateusz Morawiecki accused the EU of "blackmail" on Tuesday in a public clash with European Commission chief Ursula von der Leyen over his country's rejection of parts of EU law. The row, played out in the European Parliament, underlined the seriousness of the issue which both Brussels and Warsaw say threatens the cohesion of the 27-nation bloc.
