Johnson aims at EU over post-Brexit rules

Prime Minister Boris Johnson on Monday renewed British threats to break a Brexit agreement with the European Union, blaming it for a crisis that’s blocking the formation of a new government in Northern Ireland.

Johnson said there would be “a necessity to act” if the EU doesn’t agree to overhaul post-Brexit trade rules that he says are destabilizing Northern Ireland’s delicate political balance. He held private talks with the leaders of Northern Ireland’s main political parties.
