The North’s Deputy First Minister Martin McGuinness has conceded that a hard border between Ireland and the North will be hard to avoid.
McGuinness’ comments come as the British Irish Chamber of Commerce has said we need to start thinking about how we will continue trading with the UK, in the wake of the Brexit vote.
Sinn Féin has called for a poll on a united Ireland following the referendum.
Mr McGuinness has said the return of checkpoints would be “dismaying”.
“I certainly think it’s (a hard border) more a probability than a possibility,” said McGuinness.
“I live in Derry city, (I) travel regularly to Moville, to Buncrana, to Letterkenny – roads where there were massive British army checkpoints for almost 25 years.
“To see the return of hard checkpoints along that border I think would be absolutely dismaying and disappointing.”
