Brexit civlil war: Boris faces unexpected crisis as top team SPLINTERS over US trade deal

Sam Lowe, a trade expert at the Centre for European Reform think-tank, said a trade deal could be done with the Trump administration if there was a “big offer” on agriculture.

But he warned concessions "might prove controversial with British farmers and consumer".

He said: “The US has long seen its beef, chicken and pork shut out of European markets because of high tariffs and restrictive regulations.

"If the UK is able to table an offer that deals with all of these concerns, then a trade deal can be done."
