The United Kingdom and the European Union have struck an outline Brexit deal after days negotiations but it still needs to be approved by both parliaments. In the UK, both the Labour Party and the Northern Ireland Democratic Unionist Party have denounced the outline. Critically, the DUP is an essential member of Prime Minister Boris Johnson’s coalition. Hours before a summit of all 28 EU national leaders, European Commission President Jean-Claude Juncker said Thursday: “We have one. It’s a fair and balanced agreement for the EU and the U.K., and it is testament to our commitment to find solutions.” Prime Minister Boris Johnson tweeted the two sides had struck a “great new deal,” and urged UK lawmakers to ratify it in a special session on Saturday.
