The European Union is on course for a clash with British Prime Minister Boris Johnson after Commission President Ursula von der Leyen warned it will be "impossible" to get a full deal before his year-end deadline.
In her first major intervention on Brexit since she took up her post on Dec. 1, Ms. von der Leyen said the EU is "ready to work day and night" to strike a deal but warned Mr. Johnson that there isn't time for detailed negotiations on all aspects of the U.K.'s future relationship with the EU.
The time is "very, very tight," Ms. von der Leyen told an audience at the London School of Economics ahead of a meeting with Mr. Johnson later in the day. "It's not all or nothing, it's a question of priorities," she said. As the two met, Mr. Johnson's spokesman, Jamie Davies, hit back, insisting the U.K. is still aiming for a Canada-style free trade agreement by the end of the year.
After nearly three years of bad-tempered negotiations on the U.K.'s withdrawal from the EU, both sides are now digging in on the next phase of talks as Britain prepares to leave the bloc on Jan. 31. Once the separation is complete, negotiations will formally open on the future trading relationship between the U.K. and the EU.
