BRUSSELS/LUXEMBOURG (Reuters) -Poland's prime minister came under repeated criticism during a tense debate in the European Parliament on Tuesday, with the EU's chief executive telling Warsaw that its challenge to the supremacy of EU law would not go unpunished.

Poland's relations with the European Union, already badly strained, took a big knock last week when its Constitutional Tribunal ruled that elements of EU law were incompatible with the Polish constitution.
