EU, Britain reach new Brexit deal

"Where there is a will, there is a #deal we have one! It's a fair and balanced agreement for the EU and the UK and it is a testament to our commitment to find solutions," said Juncker hours before Thursday's EU summit.

"We now have a newly agreed Protocol that protects peace and stability on the island of Ireland and fully protects our Single Market. I hope that we can now bring this over the line and provide the certainty our citizens and businesses so deserve," he noted in a press release published by the Commission on its website.

British Prime Minister Boris Johnson earlier in the day informed a Brexit deal has been struck between the United Kingdom (UK) and European Union (EU) as the talks were going on in Brussels. However, the Northern Irish Democratic Unionist Party (DUP), who are concerned over the Brexit deal cutting off Northern Ireland  from Britain in customs and regulatory terms, said they continued to oppose it.

"We’ve got a great new deal that takes back control — now Parliament should get Brexit done on Saturday so we can move on to other priorities like the cost of living, the NHS, violent crime and our environment," Johnson tweeted.

Michel Barnier, the European Commission's chief negotiator, hailed the deal as "all-win".

"We had difficult discussions over the past days. We have managed to find solutions that fully respect the integrity of the Single Market. We created a new and legally operative solution to avoid a hard border, and protect peace and stability on the island of Ireland. It is a solution that works for the EU, for the UK and for people and businesses in Northern Ireland," said Barnier in the press release.

On thorny issues like the Irish border, which is the main obstacle for the two negotiating teams, the new deal offers new measures.

First, Northern Ireland will remain aligned to a limited set of EU rules, particularly related to goods.

"This means that all of the procedures will be taken into account in Northern Ireland and not across the island. For the purpose, UK authorities will be in charge of applying the Union Customs Code in Northern Ireland," said Barnier during a press conference Thursday.

At the same time, Northern Ireland will remain in Britain's customs territory as an entry point to the EU Single Market. This will be beneficial for Britain's future trade policy, said Barnier.

"UK can apply authoritative UK tariffs on products coming from third countries, so long as those goods reviews entering Northern Ireland are not at risk of reviews entering our Single Market. However, for goods at risk of entering the Single Market, UK authorities will apply the EU's tariffs," said Barnier.

The only remaining open question seems to be VAT regime in Northern Ireland, which, according to the EU, is an important subject to avoid distortion of competition within the Single Market for goods.

According to the website of POLITICO's Europe edition, Britain has asked for Northern Ireland not to be subject to the EU's VAT rules.

It may not seem like much, but it is problematic for the EU. Because if Britain decided to lower its tax rates, there would be problems on ensuring a level playing field, POLITICO noted.

"We were working on the issue of VAT. We managed to achieve two objectives: Maintain the integrity of the Single Market but also satisfy the UK's legitimate wishes," said Barnier.

"Four years after the entry into force of the Protocol, the elected representatives of Northern Ireland will be able to decide, by simple majority, whether to continue," he added.

In another development, the Democratic Unionist Party (DUP), British Prime Minister Boris Johnson's ruling partner and the main party in Northern Ireland, said it could not support the deal, according to European media. This cast a shadow over the fate of the deal in British parliament where Johnson's conservative party doesn't enjoy a clear majority.

Following a referendum in which 52 percent of voters supported withdrawal in June 2016, the British government invoked Article 50 of the Treaty on European Union and started a two-year Brexit process which was originally scheduled to conclude with London withdrawing from the EU on March 29, 2019.

As the British parliament refused to ratify documents negotiated between former British Prime Minister Theresa May and the EU, that deadline has been extended twice.

Johnson has insisted that Britain will leave the EU, with or without a deal on Oct 31.
