Opposition wants to make it more difficult for Poland to leave EU

Poland's main opposition grouping has filed a proposal for a constitutional change that would makes it possible for the country to leave the EU only with the backing of a two-thirds majority in parliament or through a referendum.

Under the current rules, a simple majority vote in the lower house of parliament, along with the president's official notification to Brussels, is needed to take Poland out of the EU.

Now the centrist Civic Coalition (KO) wants to make it harder for Polexit to take place.

Donald Tusk, the leader of KO's backbone party, Civic Platform, said on Friday that, according to the proposed amendment to Poland's constitution, a Polexit would require a two-thirds majority in both houses of parliament or a decision of the nation expressed in a referendum.

Tusk said Poland needed "a cast-iron guarantee that it will stay in the EU as long as this is what Poles want."

"We don't want anyone to take Poland out of the EU in a night vote by a simple majority at the request of a Euro-sceptic party," Tusk said.

The KO leader was referring to recent criticism of the EU from leading politicians from Law and Justice (PiS), the dominant party in Poland's ruling coalition.

In mid-September, Tusk accused his main adversary, PiS leader Jaroslaw Kaczynski, of planning an ultimate "Polexit."

"The statements and actions of the ruling party have clearly shown that Poland's presence in the EU is in danger," Tusk said.

Poland's conservative government has been embroiled in a number of protracted conflicts with the EU in a number of areas, most notably over the country's reforms of the justice system which, according to Brussels, violate judicial independence.

Despite the tension between Brussels and Warsaw, the Polish government has stressed it remains a committed EU member and has no intention of leaving the bloc.

In a survey conducted in September by researcher United Surveys for the daily newspaper Dziennik Gazeta Prawna and radio broadcaster RMF FM, 88 percent of Poles expressed a desire to remain in the bloc, while only 7 percent wanted to leave.
