PROSECUTORS in Poland are investigating commentators who “joked” on a right-wing television station that migrants should be sent to Auschwitz or tattooed or microchipped as a part of European reforms.

Some companies have pulled advertising from the broadcaster over the past week after guests on TV Republika made the remarks.

The private station’s role as a platform for conservative views grew after the right-wing Law and Justice party lost control of the government and public media, which it had been using to cast large-scale migration into Europe as an existential danger.
