Poland's main parties, PiS and PO, to oppose EU treaty change

Poland’s main two parties, the national-conservative Law and Justice (PiS) and centrist Civic Platform (PO), have declared that they will oppose proposed changes to the EU treaties when they come before the European Parliament (EP) this week.

PO’s leader, former European Council president Donald Tusk, today warned that the ideas epitomise the kind of “naive euro-enthusiasm” that pushed the UK to leave the EU.
