Onvrede in Polen over Duitse actiegroep die schadevergoeding claimt wegens uitzetting na Tweede Wereldoorlog (en)

Poland's prime minister Jaroslaw Kaczynski has suggested Germany is going through a "re-nationalisation of politics" in reaction to a legal complaint by a group seeking compensation for Germans expelled from Poland after WWII.

"We observe in Germany a process deeper than a simple attitude of one government or another. It's a re-nationalisation of politics, an exceptionally radical calling into question of historical judgements," Mr Kaczynski told Polish daily Rzeczpospolita in an interview published on Saturday (16 December).

He was reacting to the move by the private group "Preussische Treuhand" to take the complaint on behalf of 22 Germans expelled from Poland after the war to the Strasbourg-based European Court of Human Rights.

The case is viewed as a potential bombshell in Warsaw as it could become a precedent for hundreds of other cases.

The Polish prime minister insisted in Saturday's interview that "Germany hasn't fully explained its legal position faced with property in Poland. Its declarations in this area remain insufficient."

His twin brother - Poland's president Lech Kaczynski - voiced similar views in Brussels during last week's EU summit, warning that using European mechanisms such as the Strasbourg court "could have a damaging impact on the relations of two big European nations."

The issue, dating back to post-1945 events when Poland received some of Germany's land after the defeat of the Nazis, has been causing rifts for some time.

The German government as well as expellee groups have publicly distanced themselves from the "Preussische Treuhand," but Warsaw has criticised chancellor Angela Merkel for her reluctance to sign a treaty suggesting that both parties would abandon future financial claims.
