Political leaders in Europe on Thursday hailed the belated sealing of a UK-EU post-Brexit deal that aims to lay the groundwork for long-term future cooperation.

Britain

British Prime Minister Boris Johnson lauded what he termed "a good deal for the whole of Europe," which offers "a new stability and a new certainty" to relations.

Former prime ministers David Cameron and Theresa May, who both resigned over Brexit, dubbed the deal "very welcome". May said it "provides confidence to business and helps keep trade flowing".

European Union

Chief EU negotiator Michel Barnier warned "this agreement will require efforts," and notably pledged support to EU fishermen and women after fishing proved the toughest of issues to resolve.

Malta

Prime Minister Robert Abela said the deal would help Malta and the UK foster a stronger relationship, benefiting citizens and business.

"The European Union and UK’s renewed partnership will serve as a foundation for Malta’s relationship with the UK," he wrote on Twitter.

Ireland

Irish Prime Minister Micheal Martin said the deal "represents a good compromise and a balanced outcome" which will avoid a hard border on the border with Northern Ireland, stressing "the UK will always be a close friend and partner".

Germany

German Chancellor Angela Merkel said she was "confident" the deal represents a "good outcome" that Germany would be able to support.

Spain

Spanish Prime Minister Pedro Sanchez tweeted "the principle of an agreement between the EU and the United Kingdom is welcome," while adding that Madrid and London must continue talking on the status of Gibraltar.

Netherlands

"Excellent news that an agreement on a new EU-UK partnership has been reached after tough negotiations," Dutch Prime Minister Mark Rutte tweeted, complimenting Michel Barnier and European Commission chief Ursula von der Leyen for "their tireless efforts".

Portugal

"I warmly welcome the reaching of an agreement with the United Kingdom," Portuguese Prime Minister Antonio Costa tweeted, underlining that the UK will remain an important partner and ally.

Italy 

"Good news: deal between the EU and the UK has been agreed," tweeted Italian Prime Minister Giuseppe Conte. "Interests and rights of European businesses and citizens guaranteed. The UK will be a central partner and ally for the EU and Italy."

Northern Ireland

"This is the start of a new era in the relationship between the UK and the EU and in Northern Ireland we will want to maximise the opportunities the new arrangements provide for our local economy,” said First Minister Arlene Foster.

Scotland

"Before the spin starts, it’s worth remembering that Brexit is happening against Scotland’s will. And there is no deal that will ever make up for what Brexit takes away from us. It’s time to chart our own future as an independent, European nation," said First Minister Nicola Sturgeon. 

France

"Europe's unity and firmness paid off," tweeted President Macron, adding "the agreement with the United Kingdom is essential to protect our citizens, our fishermen, our producers" and concluding that "Europe is progressing, and can look to the future, united, sovereign and strong".

Austria

"I welcome that an agreement could be reached by the negotiators on the EU's future relationship with the UK. We will now carefully examine the agreement," tweeted Chancellor Sebastian Kurz.

Romania

"Romania welcomes the agreed partnership on future relations. This agreement will protect the interests of companies & citizens -- Romania’s key objectives during these negotiations," tweeted President Klaus Iohannis.

Denmark

"Draft agreement is the best Christmas gift EU27 & UK can give each other," tweeted Foreign Minister Jeppe Kofod.

Greece

"European unity remained strong through an arduous process, while EU member states' interests were protected. Now we can build a mutually beneficial relationship between the EU and the UK," Greek Prime Minister Kyriakos Mitsotakis said in a tweet.

Finland

Finland’s Europe minister Tytti Tuppurainen tweeted that the news of a deal was "excellent". But the minister warned that it would be a more distant relationship in future. "Businesses in particular should be ready for this weakening."

Sweden

"Important step for the further development of ties between UK and EU as well as between UK and Sweden", said Swedish Foreign minister Ann Linde on Twitter.

Czech Republic

Czech Foreign Minister Tomas welcomed the deal as "the end of uncertainty". "We are facing 2,000 pages of reading and analyses, but I believe it's good news," he tweeted.
