Brexit, the border and a bruising day of brinkmanship
Row as Robinson tells Dublin: wind your neck in
MPs say frictionless frontier looks impossible
Republic’s officials accuse UK of smears
A war of words over the Irish border saw relations between leaders in London, Dublin and Belfast plummet last night as crunch Brexit talks loom.
Former DUP leader Peter Robinson told Dublin to "wind its neck in" on the border issue, and his party threatened to collapse the Tory government over a plan that would see Northern Ireland continue to operate EU customs rules after Brexit.
Meanwhile, Westminster's Brexit committee warned that the return of border checkpoints seems "inevitable", and Dublin officials accused London of a smear campaign against Taoiseach Leo Varadkar.
