"Deal or no deal, the Withdrawal Agreement must be respected," European Commission Vice President Maros Sefcovic told the European Parliament.
Sefcovic said the EU is committed to reaching a deal on the trade agreement and other aspects of their future relationship, but that the two sides remain "far apart" on the issues of fisheries and the so-called level playing field of fair competition.
"Our objective is still to reach an agreement that will pave the way for a new fruitful relationship between the EU and UK. We will continue to work for such an agreement, but not at any price," he said.
