Two prominent members have left Law and Justice, Poland’s main opposition party in a dispute over the coming elections to the European Parliament.

Deputies Marcin Libicki, his son Jan Filip Libicki and a third, MEP Jacek Tomczak resigned from the party after it refused to support Mr.Libicki senior’s candidature to the Euro-elections, following media suggestions that he had collaborated with security services in communist times.

The loss of the two deputies also means that the government might have enough votes in Parliament to muster the two-thirds majority needed to change the constitution.

This could open the way for Prime Minister Donald Tusk to introduce the legislative changes allowing Poland to enter the eurozone in 2012, so far opposed by eurosceptics Law and Justice.
