BRUSSELS (Reuters) - There may be a narrow path to a new trade pact with the United Kingdom but some substantial gaps remain, an EU diplomat said on Monday. “There might be a narrow path to an agreement visible - if negotiations can clear the remaining hurdles in the next few days,” said the diplomat, adding that some progress was made over the last few days of the EU-UK talks. “But - sometimes substantial - gaps still need to be bridged in important areas like fisheries, governance and level playing field... Success depends on whether London also wants a fair deal and is ready to accept the inherent trade-offs,” the diplomat said.
