Poland's ruling party has proposed new legislation concerning the Constitutional Tribunal that, it says, should calm the political storm surrounding the special court.

The conflict between the ruling right-wing Law and Justice party and the pro-EU opposition over control of the court has led to street demonstrations by both sides and has provoked concerned comments from some leaders in the EU.

On Thursday, Law and Justice presented in Parliament new legislation that, it said, should calm the dispute and strengthen the court. The proposal increases the number of judges, requires a two-thirds majority for its rulings instead of the current simple majority, gives the power to swear in judges to parliament instead of the president and moves its headquarters out of Warsaw.
