"If Britain leaves the European Union without a withdrawal agreement, Ireland could be faced with both security and constitutional threats," Irish Prime Minister Leo Varadkar said on Thursday August 1st as reported by Reuters.
"I think we should be afraid of a no-deal Brexit. A no-deal Brexit would have impacts on the economy north and south and in Britain. It could have security implications as well and it could have constitutional implications," Varadkar told journalists.
"It could have security implications as well and it could have constitutional implications."
Varadkar said he had noticed "heightened rhetoric" around Brexit but said it had not come from the Irish government, whose message was "very measured and very consistent."
Varadkar also said it remained to be seen if Johnson could be viewed as impartial in dealing with talks between Irish nationalists and pro-Brexit unionists in Northern Ireland, but that he should be given a chance.
Currently Johnson’s Conservative Party relies on the support of Northern Ireland’s Democratic Unionist Party in the UK Parliament.
"He has only just started in the job and I think we need to give him a fair wind and a decent chance," Varadkar said, referring to the new UK prime minister.
