Irish PM Martin warns Britain over its N.Ireland law

Irish Prime Minister Micheal Martin warned Britain on Sunday it would be "very serious" if it enacted a new law to unilaterally change part of a Brexit deal to try to ease trade with Northern Ireland, and urged the government to resume talks. "If this bill is enacted, I think we're in a very serious situation," he told the BBC.

"What now needs to happen is really substantive negotiations between the British government and the European Union."
