If the British government deviates from the exit agreement, "it is a clear breach of contract that destroys our confidence in London," said the chairman of the trade committee in the European Parliament, Bernd Lange, of the "Frankfurter Allgemeine Zeitung" (Thursday edition). "We must then stop the negotiations on the future relationship until the UK government returns to the treaty."
The SPD politician called the British Northern Ireland Minister's announcement that London would break international law a “calculated provocation”. And further: "Northern Ireland must not become a dumping zone in the European internal market," said Lange, who is a member of the European Parliament's Brexit coordination group. The chairman of this group, the CDU politician David McAllister, expressed himself more cautiously. "The concrete implementation of the exit agreement is a litmus test for future partnership and has an impact on the UK's credibility to comply with legally binding international treaties," he told the FAZ. The British government is obliged to comply with international law and to implement the withdrawal agreement. "That is essential for the success of our future partnership."
