Following the UK's withdrawal from the EU on 31 January 2020,[a] the UK continued to conform to EU regulations and to participate in the
EU Customs Union during the "
Brexit transition period", which began on 1 February 2020 and ended on 31 December 2020. This allowed for a period of time to negotiate a bilateral
trade agreement between the UK and the EU.
Developments
Timeline
23 January 2023: Shadow Foreign Secretary
David Lammy, in a speech at
Chatham House, announced that if elected the next Labour government would use the next scheduled review of the
TCA to increase cooperation with the EU.[1]
Since May 2022, opinion polling has shown a steady increase in the numbers of Britons seeking to rejoin the European Union, with the number polled opting to stay outside the EU declining.
In November 2022, 53% of Brits polled would opt to re-join the EU if another referendum were held, with 34% opting to stay out (14% unsure).[3]
The UK has decided to withdraw from the
single market, the
customs union. Furthermore for all international agreements the EU entered into, the EU participation does not include the UK since 1 January 2021.[4]
Those definitive changes could create difficulties which might be under-estimated, according to
Michel Barnier:[4]
re-introduction of customs formalities, as was the case before UK membership, for every product imported and exported to and from the EU and the UK
end of financial passporting rights for the UK services sector
end of
Community preference to all goods, trade and people from the UK in EU member states
UK product certification will no longer be recognized within the EU
Post-Brexit negotiations have tried to create an ambitious pact between the UK and the EU to avoid disruption as much as possible, according to Michel Barnier.[4]
The UK could have sought to continue to be a member of the
European Economic Area, perhaps as a member of
EFTA. In January 2017,
Theresa May, the
British Prime Minister, announced a 12-point plan of negotiating objectives and said that the UK government would not seek continued membership in the
single market.[5][6]
The EEA Agreement and the agreement with Switzerland cover free movement of goods, and
free movement of people.[15][16] Many supporters of Brexit want to restrict freedom of movement;[17] the Prime Minister ruled out any continuation of free movement in January 2017.[6]
In 2023, the French government proposed legislation allowing British people who own a home in France to stay there without limit, but the Constitutional Court rejected it as unconstitutional. Therefore, like other visa-free nationals, they can stay in France for a maximum of 90 days per 180-day period, unless they get a residence permit.[18]
Science and technology
Scientific research
The UK and EU came to an agreement in September 2023 for the United Kingdom to rejoin the European Union's funding programme for scientific research,
Horizon Europe.[19]
One aspect of the final withdrawal agreement is the specific or unique status of
Northern Ireland.[20] The
Northern Ireland Protocol that is part of the agreement provides (inter alia)
Northern Ireland remains legally in the UK Customs Territory, and can be part of any future UK trade deals, as long as it is consistent with the Protocol. This results in a de jure customs border on the
island of Ireland, between Northern Ireland and the Republic of Ireland.[21][22]
Great Britain is no longer in a
customs union with the European Union. Northern Ireland is also no longer legally in the EU Customs Union, but remains an entry point into it, creating a de facto customs border down the
Irish Sea.[23][21][22]
Level playing field provisions applying to Great Britain have been moved to the non-binding Political Declaration, although they are still present for Northern Ireland within the protocol.
The UK needs to follow — in respect of Northern Ireland — EU regulations with regards to trade in goods and to implement future changes of those regulations;
The Court of Justice has jurisdiction with regards to non-compliance of the UK with parts of the protocol as well as with the application of the trade in goods-regulation. Regarding the application of these rules courts can (and sometimes must) in regards to Northern Ireland make preliminary reference to the
CJEU.
EU
tariffs (which ones are dependent on a UK–EU
trade agreement), collected by the UK on behalf of the EU, would be levied on the goods going from Great Britain to Northern Ireland that would be "at risk" of then being transported into and sold in the Republic of Ireland; if they ultimately are not, then firms in Northern Ireland could claim
rebates on goods where the UK had lower tariffs than the EU. A joint EU–UK committee will decide which goods are deemed "at risk".[23][22]
A unilateral exit mechanism by which Northern Ireland can leave the protocol: the
Northern Ireland Assembly will vote every four years on whether to continue with these arrangements, for which a simple majority is required. If the assembly is suspended at the time, arrangements will be made so that the
members of the legislative assembly can vote. If the Assembly expresses
cross-community support in one of these periodic votes, then the protocol will apply for the next eight years instead of the usual four. If the Assembly votes against continuing with these arrangements, then there will be a two-year period for the UK and EU to agree to new arrangements, with recommendations made by a joint UK–EU committee.[23][22] Rather than being a fallback position like the
backstop was intended to be, this new protocol will be the initial position of Northern Ireland for at least the first four years after the
transition period ends in December 2020.[20]
According to Michel Barnier, this might raise issues for Northern Irish companies which need the UK to deliver clarity on this topic.[4]
