Sterling is apparently lifted today by news that EU’s Brexit negotiating team told EU diplomats that a deal is “very close”. And, both sides are working closely for the the summit on October 17-18 first, and then the final one on November 17-18.
Between now and then, October 10 is a key date when EU chief negotiator Michel Barnier will present to European Commission a first draft of the “Outline of new partnership with UK”. That’s for the trade relationship with UK after Brexit.
The issue on Irish border must be cleared before October 17-18 so as for EU to determine that enough progress is made for moving on the the emerging summit in November, when everything would be finalized.
