EU leaders are due to meet in Salzburg, Austria later this month for an informal summit at which they will reportedly discuss a bid to break the Brexit impasse, in a move characterised as a “save Theresa” operation.

According the Financial Times, the summit will see leaders discuss whether or not to issue new instructions to Mr Barnier, the bloc’s chief Brexit negotiator, amid UK concerns his approach so far has been too inflexible. One of the most important topics of the Salzburg discussion will be the form of the “political declaration” planned for future relations, and the level of detail and precision that is required.
