Boris Johnson to lay out Brexit trade deal priorities within week

Boris Johnson is set to lay out the UK's negotiating priorities for a trade deal with the EU within a week, firing the starting gun on post-Brexit talks.

Britain's last minister to ever attend an European Council meeting paid farewell to his counterparts without pomp on Tuesday, marking the end of the UK's participation in the regular system of ministerial meetings.

Christopher Pincher paid farewell to his European counterparts with a standard-issue government line, telling a packed briefing of journalists that "while we are leaving the institution of the EU we are not leaving Europe".

"We are very clear that we are an optimistic, outward looking free trading nation and we will look for friendly cooperation with the European Union based on our free trade agreement as set out in the political declaration," he said.

The Foreign Office minister added: "We're looking forward to a different world, a different relationship with our friends, our neighbours, and our partners in the EU."

It emerged this week that the UK is set to resist EU demands for the European Court of Justice (ECJ) to have a say over UK trade after Brexit – putting the two sides on a collision course in upcoming talks.

Brussels wants the ECJ to have a role deciding disputes that arise in the course of trade – effectively giving it continued power over the UK.

But Brexiteers regard the ECJ as a “foreign court”. The UK currently has a say in appointing its judges and makes EU law in common with other member states – but will lose all these powers next month after it leaves.

The issue joins several others as likely to cause problems: like whether Britain signs up to a strong regulatory “level playing field”, and the extent to which EU fishing fleets will have access to British waters.

Brussels has suggested that fishing access could be traded for access for UK financial services firms on the continent – a major component of the British economy.

The Times newspaper reports that Downing Street regards the court as “by very definition not a neutral arbiter”.

EU trade officials say they believe ECJ involvement is necessary to “ensure consistent interpretation of the agreement and secure the role of the [ECJ] in this respect”.

Some EU trade arrangements with its neighbours already include a role for the ECJ. Under the terms of the Ukraine association agreement, any issues considered that cross into EU law are put the ECJ to make a binding ruling.

By contrast, looser trade agreements like CETA, which the EU signed with Canada, do not rely on the Luxembourg supreme court.

Countries with close relationships with the EU like Norway and Iceland, which are members of the European Economic Area (EEA), are more strongly under the jurisdiction of the court.
