Brexit bust-up torpedoes Johnson’s bid to showcase ‘global Britain’

Northern Ireland border row hits G7 summit in Cornwall as prime minister tells other leaders UK is a single country'

Boris Johnson was embroiled in an extraordinary public spat with EU leaders over Northern Ireland yesterday as tensions over Brexit boiled over at the G7 summit in Cornwall.

After a series of tense bilateral meetings at which the French president Emmanuel Macron, the German chancellor Angela Merkel and the European Commission president Ursula von der Leyen, told their summit host the UK must implement the Brexit deal in full, an unrepentant Johnson said he had urged his EU colleagues to get it into their heads" that the UK is a single country".
