Protestant unionists are queuing for Irish passports in Belfast and once quiet Catholic nationalists are openly campaigning for a united Ireland, signs of deep shifts in the United Kingdom's most troubled province since Britons on June 23 voted to leave the EU.
Eighteen years after a peace deal ended decades of fighting between mainly Catholic nationalists who favor a united Ireland and mainly Protestant unionists who favor remaining part of the United Kingdom, Britain's Brexit vote is making people on both sides of the divide in Northern Ireland think the unthinkable.
Northern Ireland, like neighboring Scotland, voted to stay in the European Union, with 56 percent in favor, even though Britain as a whole voted to leave the bloc.
