Poland's president signs constitutional court bill amendment
President Andrzej Duda, a close ally of the ruling conservative Law and Justice (PiS) party which had drafted the bill, is due to make a statement at 1100 GMT, the chancellery said in a statement.
The contentious amendment increases the number of judges needed to pass judgements and change the order in which cases are heard. The opposition has said it could paralyse the court's work and make it difficult for its politicians to challenge the new ruling party's legislation.
