LONDON—Britain said on March 6 it was pushing forward with plans to find alternative arrangements to eliminate the need for an Irish “backstop” in Prime Minister Theresa May’s Brexit deal, part of a bid to break the impasse weeks before Britain exits the EU.
Britain is due to leave the bloc on March 29 but no withdrawal deal is in place after British lawmakers rejected May’s treaty in part due to the backstop, an insurance policy to stop the return of a hard border between the British province of Northern Ireland and the Irish Republic after Brexit.
