LONDON- British negotiator David Frost said on Sunday that the European Union needs to change its attitude if talks this week on the Northern Irish Brexit protocol are to be successful.

"The EU needs a new playbook for dealing with neighbours, one that involves pragmatic solutions between friends, not the imposition of one side's rules on the other and legal purism," Frost wrote in an opinion piece published by the Financial Times.
