Luxembourg Foreign Minister Jean Asselborn has questioned Poland’s place within the EU, telling German newspaper Tagesspiegel that “today’s Poland under Jaroslaw Kaczynski could be an EU member no longer”.

He went on to argue that Poland “no longer respects the Copenhagen criteria that the country had to meet before EU accession”.

“The government in Poland is more and more involved in restricting the rule of law,” he said, adding that the country may have been emboldened by the recent actions of Hungary.

“But there is something else in Poland,” he said. “Jaroslaw Kaczynski, the head of the PiS government division, is an ideologue. He believes the EU is a brake-pedal for Poland.

“He wants to create a right-wing conservative social order based on nationality.”

This is not the first time Asselborn has publicly criticised a fellow member state.

In September, he called for Hungary to be suspended from the EU for violating democratic “core values” and treating refugees like “animals”.
