Sinn Féin's national chairman Declan Kearney said the question of Northern Ireland remaining as part of the UK had now been brought into sharp focus, reports RTE News.
"We have a situation where the north is going to be dragged out on the tails of a vote in England," he said.
"That is a huge democratic deficit for our society, building on the existing democratic deficit of partition.
"The British Government have now forfeited its mandate to represent the north of Ireland in relation to the European Union."
He added: "We now have a situation where Brexit has become a further cost of partition, a further cost of the Union and Sinn Féin will now press our demand, our long standing demand, for a border poll."
