Donald Tusk, a former European Union Council president whose longstanding ties to Brussels have cast him as both a savior and a scapegoat in Poland’s toxic political landscape, said on Saturday he planned to temporarily halt the right to claim asylum in Poland – adding he’d fight the EU on the matter if he needed to.

“It is our right and our duty to protect the Polish and European border. Its security will not be negotiated. With anyone,” Tusk wrote on social media.
