LONDON—Prime Minister Boris Johnson urged European Commission President Ursula von der Leyen on Thursday to consider seriously Britain’s proposals to change what he called the “unsustainable” way a Brexit deal is governing trade with Northern Ireland.
Since it completed its exit from the EU at the end of last year, Britain’s ties with the bloc have reached new lows, with both sides accusing each other of acting in bad faith over an agreement for post-Brexit trade with Northern Ireland.
