The Polish government is accusing Germany of acting unilaterally and unfairly over its “unacceptable” plans to introduce temporary controls into in the passport-free Schengen zone at all the country’s nine land borders, in what Warsaw says is a contravention of European law.
Donald Tusk, the Polish prime minister, said Germany had introduced a “de facto suspension of the Schengen agreement on a large scale” after the interior minister, Nancy Faeser, announced Berlin’s decision to confront what she called “irregular migration” by introducing spot controls along Germany’s 2,300-mile (3,700km) frontier after a recent spate of suspected Islamist attacks.
