A long-awaited blueprint for the UK’s relations with the EU will be published later, with ministers vowing to deliver a “practical and principled” Brexit.

The “comprehensive vision” for future trade and co-operation is aimed at ensuring global trade deals and no hard border in Northern Ireland.

Brexit Secretary Dominic Raab said it would respect the result of the 2016 Brexit vote and address business needs.

The EU’s chief negotiator has insisted the proposals must be workable.

The UK is set to leave the EU on 29 March 2019, more than two and half years after the public voted by a margin of 51.9% to 48.1% for Brexit, in a referendum.

The two sides are negotiating outstanding issues related to its departure as well as the outline of their future relationship once a proposed transition period comes to an end, on 31 December 2020.

Both are aiming for an agreement by October, to allow enough time for the UK and European parliaments to vote on what is decided.

The EU’s chief Brexit negotiator Michel Barnier said the UK initiative needed to be compatible with EU guidelines and not create extra costs and red tape.

He said: “We will look carefully at each and any proposal of UK, but these proposals must be workable.”

Why is this document so important

It is a set of proposals the government hopes will be the foundation of the UK’s future relationship with the EU.

It lays out, in more detail than has ever been seen before, how the UK would like to trade and co-operate with the EU for years and decades to come.

The White Paper, reportedly delayed for several months amid disagreements between ministers, was finally approved by Theresa May’s cabinet at her country residence, Chequers, last week.

The main points are:

• The UK will maintain a “common rulebook” for all goods traded with the EU, including agricultural products
• A treaty will be signed committing the UK to “continued harmonisation” with EU rules – avoiding friction at the UK-EU border, including Northern Ireland
• Parliament will oversee the UK’s trade policy and have the ability to “choose” to diverge from the EU rules
• There will be different arrangements for services, with greater regulatory flexibility
• A “joint institutional framework” will be established to interpret UK-EU agreements
• The European Court of Justice will no longer have jurisdiction in the UK – but UK courts will have to pay “due regard” to EU case law in areas of complete alignment with EU rules
• The borders between the UK and EU will be treated as a “combined customs territory”
• The free movement of people between the UK and the Continent will end
• A “mobility framework” will be set up to allow UK and EU citizens to travel to each other’s territories

Mr Raab, who replaced David Davis on Monday, said it struck the right balance between protecting existing arrangements with the EU and freeing up the UK to look further afield.

“This government is determined to make sure the UK is ready to lead the industries of the future and seize the opportunities of global trade,” he said.

“At the same time, we need to cater for the deeply integrated supply chains that criss-cross the UK and EU and which have developed over our 40 years of membership.

“It is a vision that respects the result of the referendum and delivers a principled and practical result.”

This is far from the final deal, only the UK’s opening offer to the EU’s 27 other members. The EU has welcomed its publication and said it will respond when it has seen the plans in detail.
