Irish drivers warned over 'no-deal' Brexit as EU and UK talk Ireland's deputy prime minister says the European Union wants to work with Britain to ensure there is a Brexit deal.

LONDON -- Ireland's deputy prime minister said Thursday that the European Union wants to work with Britain to ensure there is a Brexit deal, as Irish drivers were warned they will need new paperwork to cross the currently invisible border to Northern Ireland if the U.K. leaves the bloc without an agreement.

The Motor Insurers' Bureau of Ireland said it has supplied insurance companies with 1 million forms so customers can apply for the internationally recognized "Green Card" proof of insurance documents.

British drivers traveling to Ireland or other EU countries will also need the paperwork — just one of a host of new rules and hurdles citizens will need to negotiate if Britain crashes out of the bloc without a framework over its departure.

Currently, auto insurance in any EU country covers the whole bloc. If Britain leaves with a deal, there will be no change until at least the end of 2020.

Britain is due to leave the 28-nation bloc on March 29, but lawmakers have rejected the divorce deal Prime Minister Theresa May negotiated with the EU, raising the prospect of a chaotic "no deal" Brexit.

Governments in EU countries, as well as in Britain, have warned citizens and businesses to prepare for potential disruption to trade and travel as tariffs, customs checks and other barriers are erected between Britain and its biggest trading partner.

But U.K. authorities acknowledged this week that neither individuals nor businesses are ready for a "no-deal" departure, and "the short time remaining before 29 March 2019 does not allow government to unilaterally mitigate the effects of no deal."

British lawmakers rejected May's deal with the EU last month, largely over a provision to guarantee there are no customs posts or other barriers along the Irish border. The mechanism, known as the backstop, is a safeguard that would keep the U.K. in a customs union with the EU to remove the need for checks until a permanent new trading relationship is in place.

May wants to revise the deal to reassure opponents that the backstop would only apply temporarily. But EU leaders insist that the legally binding Brexit withdrawal agreement can't be reopened.

Irish Deputy Prime Minister Simon Coveney said the EU "wants to work with the U.K. to try to give the reassurance and clarification" it needs on the border issue.

But he said the EU had made it "very clear" that the text of the withdrawal agreement will not be reopened.

"What they'll be providing will be an addition, but in a way that doesn't undermine the meaning of that text, which I think is very important from an Irish perspective," Coveney said in Dublin.

May says U.K. lawmakers will get to vote again on her deal — including any amendments she secures — by March 12. If it is rejected, Parliament will then vote on whether to leave the EU without an agreement or seek to postpone Brexit by up to three months.

The move has angered pro-Brexit lawmakers, who fear a delay could be used to try to stop Britain leaving the EU.

A junior minister in May's government, George Eustice, quit Thursday, saying that postponing Brexit would be "the final humiliation of our country."

"We cannot negotiate a successful Brexit unless we are prepared to walk through the (exit) door," said Eustice in a letter resigning as agriculture minister.

Any delay would require approval from all 27 remaining EU nations.

Austria's leader said Thursday that if Britain seeks an extension to prevent a disorderly exit, Vienna would back it. But Chancellor Sebastian Kurz said he wanted to see Britain leave before European Parliament elections in late May.

Kurz said that "the participation of a country that wants to leave the European Union in European Parliament elections would, I think, seem more than absurd."

Speaking after meeting Kurz in Vienna, chief EU Brexit negotiator Michel Barnier said any delay "must serve not to put off the problem but to resolve the problem" in the British Parliament.

"Today, above all we need decisions, much more than extra time," he said.
