Former UK Prime Minister Tony Blair, who was a key figure in the Good Friday agreement, which eased sectarian tensions in Northern Ireland, responded to those calling to change the agreement for the sake of Brexit.
Blair told Euronews that: "They (Brexiteers) are saying this now because anything that stands in the way of Brexit - and the Good Friday agreement is a complication for the Brexit people - they are prepared to get rid of it even if it means that the peace in Northern Ireland is put at risk. It's a totally irresponsible position."
Blair's comments come as current UK Prime Minister Theresa May was also challenged over her plans for the Irish border by European Council president Donald Tusk in Downing Street.
Tony Blair told Euronews: "that the critical thing is you can't re-run the referendum but what you can do is say the British people have the right to have the final say on the final deal ... "
"Parliament first have have got to consider it - now I think Parliament will find it hard to reach an agreement - if they dont reach an agreement then its open to go back to the people and let the people make the final choice."
