Britain’s new exit date from the EU, and the conditions attached to a Brexit delay, will likely be fixed in the gilded rooms of the Belgian prime minister’s 16th century Egmont Palace hours before Theresa May addresses the leaders.

Under emerging plans, a small group of EU leaders whose countries will be most affected by the UK’s departure will be hosted by the Belgian PM, Charles Michel, on Wednesday afternoon. The guest list is likely to include the leaders of France, Germany, Spain, the Netherlands, Denmark and Ireland.
