DUP Deputy Leader Nigel Dodds has criticised Taoiseach Leo Varadkar after he said Brexit talks could continue in the new year if agreement is not sealed by next week.
Earlier today Mr Varadkar told the Dáil: "We want to move to phase two but if it is not possible to move to phase two next week because of the problems that have arisen, well then we can pick it up of course in the new year."
Mr Dodds said: “Leo Varadkar's statement about the Brexit talks continuing into the new year will send more worries through the business and commercial sectors of the Irish Republic than it will in Northern Ireland or the rest of the United Kingdom.
"The longer there is delay in getting onto the second phase of the negotiations about a trade deal, the greater the prospect of a ‘no trade deal’ outcome.
"The Irish Republic would suffer far worse economically from no trade deal than the United Kingdom.
Mr Dodds continued: "The Republic of Ireland has £13.4 billion worth of sales to the United Kingdom. It is estimated that tens of thousands of jobs are at stake.
"Mr Varadkar may try to appear calm on the surface but he is playing a dangerous game - not with us but with his own economy.”
The taoiseach said he stood by the text "agreed" between negotiators on Monday which was reportedly scuppered by a late intervention from the DUP, which said it could not accept the government's proposal that there should be continued "regulatory alignment" between Northern Ireland and the Republic.
Mr Varadkar said he intended to speak to the British prime minister in the coming days.
He acknowledged it was in the Republic's own interest to see the EU-UK negotiations proceed to their second phase and address post-Brexit trade once the European Council meets on December 14/15.
He added: "I think we should listen to all parties in Northern Ireland and not accept this idea that seems to be gaining prevalence in some parts of London and maybe other places as well that there is only one party in Northern Ireland and that party speaks for everyone.
"I don't accept that premise, which seems to be accepted by too many people at the moment."
The taoiseach said it was the UK's role to come back to the EU side with proposals.
"I understand that the prime minister has difficult issues that she is managing, there are different views within her own party on Brexit and she also has to manage a confidence and supply agreement that she has with the DUP.
"I absolutely accept that Theresa May wants to come to an agreement, that she is acting in good faith and I want to give her time ... before we move things forward."
He said it was the "desire, ambition and wish" of his government to move on to post-Brexit trade talks.
"It is in our interest to move to phase two, that is where we talk about the transition period that we need, so individuals and businesses can prepare for any long-term change.
"It is where we can talk about the new trading arrangements which are so important for Irish importers and exporters, the agri-food industry and anyone whose job in Ireland depends on trade with Britain."
The DUP MP Ian Paisley has suggested a no-deal Brexit could cost the Republic 3.8% of its GDP overnight.
Mr Varadkar said leaders needed to listen to other voices in Northern Ireland as well as Theresa May's pro-Brexit partners the DUP, as they attempted to iron out differences over the border and other issues.
The taoiseach and British prime minister spoke on the phone this afternoon.
A spokesman for Mr Varadkar said: "They took stock of developments since Monday. The Taoiseach reiterated the firm Irish position regarding the text as outlined by him on Monday.
"They agreed to speak again over the coming days."
