European Commission Vice-President Maroš Šefčovič said on Tuesday that the “full and timely implementation” of the withdrawal agreement of the U.K. from the European Union (EU) is “simply not debatable.” Šefčovič stated that Britain's decision to push ahead with its internal market bill, which explicitly broke the country's withdrawal treaty with the EU, undermined London's credibility in talks, saying it was a "heavy blow to the British signature and reliability.”
