European Commission President German Ursula von der Leyen gives a press conference to announce the names of the new European commissioners, on September 10, 2019 at the European Commission in Brussels | Kenzo Tribouillard/AFP via Getty Images Von der Leyen: UK must nominate a commissioner if Brexit date extended Incoming Commission chief says a Brit would have to join her team if UK is still an EU member on November 1.

If the U.K. is granted a Brexit extension by the EU, then it will have to nominate a European commissioner, Ursula von der Leyen said.

The president-elect of the Commission was speaking in Brussels as she unveiled the portfolios that her team will get — subject to approval by the European Parliament.

The U.K. is not part of the list as Boris Johnson has said there was no need to nominate a commissioner when the country is leaving the EU on October 31. But that was before the Westminster parliament voted to force Johnson to ask for an extension if there's no Brexit deal in place by October 19.

Von der Leyen, a former German defense minister, said the U.K. will have to nominate a commissioner if it is still a member of the bloc when the new Commission takes office on November 1.

“If the U.K. were to ask for an extension, and if that were granted, then according to the rules of the treaty, then yes, a commissioner would have to be appointed and that person would receive a portfolio,” she said.
