Prime Minister Boris Johnson said that some British lawmakers hoping to block Brexit were engaged in “terrible” collaboration with the European Union by undermining London’s negotiating hand and so making no deal more likely.

The prime minister also warned that unless EU nations agreed to compromise on Britain’s withdrawal deal leaving the bloc, then the UK “will be forced to leave with a no-deal Brexit.
