EU chief Brexit negotiator Michel Barnier on Monday signalled "some progress" in talks on a post-Brexit trade deal, EU diplomats said, but differences remain on key sticking points. "There might now be a narrow path to an agreement visible -- if negotiators can clear the remaining hurdles in the next few days," an EU diplomat said after a briefing from Barnier. "There has been some progress in the negotiations over the last few days, but -- sometimes substantial -- gaps still need to be bridged in important areas like fisheries, governance and level playing field." bur/del/bp
