There was said to have been a refreshing candidness, but there is much still left to chew over

In the final few moments, at the end of a long dinner on the 13th floor of the European commission’s Berlaymont headquarters, Boris Johnson and Ursula von der Leyen slipped away from their advisers and chief negotiators to talk alone in a corner of the room. It was a tête-à-tête between two leaders mindful of the historic nature of their discussions.

Their conversation was intense, and notable for its apparent frankness; the body language made that clear to observers. The entire evening, as Von der Leyen would later tweet, had been “lively” – but this was not two politicians merely talking past each other. Both appeared to understand each other’s point of view, sources told the Guardian, and concluded it was worth “one last go” to reach a Brexit deal, even amid warnings of increasingly gloomy prospects. A Sunday deadline was set.

PM to make trip in 11th-hour effort to break impasse, raising hopes of a deal on trade and security

Boris Johnson will travel to Brussels for a face-to-face summit with the European commission president, Ursula von der Leyen, in an 11th-hour attempt to break the impasse in the Brexit negotiations.

A long-awaited crunch meeting will be held in the “coming days”, the two leaders said in a joint statement following a phone call lasting over an hour, keeping hopes alive of agreement on a trade and security deal. Sources on both sides pointed to Wednesday or Thursday as the most likely dates.
