European Commission President Ursula von der Leyen and British Prime Minister Boris Johnson will meet on Wednesday at 10 Downing Street, the European Commission said Friday.

Downing Street confirmed the meeting, without giving further information on the timing or content.

It will be the first one-on-one meeting between the two leaders and comes after the House of Commons voted in favor of the Brexit Withdrawal Agreement on December 20, bringing the country a step closer to exiting the EU at the end of January. However, the legislative procedures in the U.K. are not yet finished and the European Parliament also still needs to approve the Brexit deal.

A main topic of conversation will likely be future relations between the two sides. Johnson has vowed not to extend the Brexit transition period beyond the end of 2020, leaving Brussels and London a mere 11 months to negotiate and ratify an agreement that covers future relations in areas from trade to transport to judicial cooperation.

Von der Leyen said in late December that she was “very worried” about the limited time to negotiate such a deal.
