I know Labour want a general election, whether there is one is doubtful , whether Labour wins is doubtful. The Tories or rather the civil service have been in non-stop discussions with the EU for the best part of two years and the Uk have got exactly what was expected. Labour / Starmer will change nothing. The 4 freedoms and the backstop are not up for discussion. The second part of the negotiation will start after the UK leaves in March if May's deal survives.
I know the UK still think, even after all this time, that the EU are just waiting around to see which cherries the UK would like and which leader will be in charge. The first part is over, either the UK go ahead with the deal, they revoke A50 or they leave with no deal. No more fantasy from the Tories or Labour.
