South Dublin County Council has voted in favour of calling on the Government to plan for a United Ireland - uniting the Republic of Ireland and Northern Ireland.
A motion was raised by Sinn Fein councillor Mark Ward at yesterday's monthly council meeting.
It also called on the British Secretary of State to set a date for a border poll on Irish Unification.
It was passed following a vote, with members of Fine Gael, Solidarity and some Independent councillors voting against it.
Speaking about the motion, councillor Ward said: “The British Brexit debacle raises the prospect of the six counties being taken out of the EU.
"The fact that Britain voted to leave the European Union must lead to a vote on a united Ireland.
“Economically, the north and south of this island are interlinked and interdependent. Countless numbers of jobs depend on an All Ireland economy with the free flow of people and goods essential for it to function.
“The reality of Brexit is that we could now have one part of the island within the European Union and another part outside. The consequences of this are self-evident in terms of the border and partition."
He continued: “When a United Ireland does happen, and it will, the political landscape on this island will be transformed. No more of the status quo.
“If the British Prime Minister is intent on a no deal Brexit, it is beholding on our Government to call for a border poll on Irish Unity under the provisions of the Good Friday Agreement.
“A border poll will allow the people of the North to self determine their future in a democratic process. The 71% of the people in the North who voted in favour for the Good Friday agreement with the knowledge that it paved a pathway to a United Ireland.
“History will tell us that Irish interests, never have or never will be served by Westminster. Partition has failed, it has stifled our island. It has halted our potential for nearly a century.
“Brexit will serve only to reinforce partition and cause further damage our island.'
