1/ Quick thread. At the end of the third week of Brexit being "done", I can only say that I'm exhausted.

Immediate pressures on companies who have been trading goods have been on grappling with all of the new customs and regulatory requirements.

There are a lot of Brexiters in the media this week making points about sovereignty, and about how the EU has not come to terms with the UK's independence.

I have some questions, which it might well be fruitful to ask them. 1/9

1. How do you understand the concept of sovereignty? What are the circumstances in which you might agree to make binding commitments to other independent states or trading blocs? 2/

2. What sort of commitments are you prepared to make in order to get trade deals with other states/blocs? And, to what end (why not trade on Australian-style terms with the wider world)? 3/

3. Do you accept that the EU has the right to impose its own rules as a condition for access to its market? Given the UK's involvement in the single market, and in the creation of its regulatory infrastructure, this feature should not come as a surprise. 4/

4. Do you accept that there is a need for borders (which were not needed while the UK was part of the single market) between states/blocs with different regulatory regimes? 5/

As the transition period ends, the #BrexitDeal applies from tomorrow. But there's also a parallel significant legal change - most of the rest of the withdrawal agreement starts to apply. A thread on the legal issues in the rest of that agreement.

The citizens' rights provisions of the withdrawal agreement (on EU citizens who moved to the UK, and UK citizens who moved to the EU, before the end of the transition period) start to apply.

Annotation and detailed analysis of those provisions here:

After today, UK citizens newly moving to the EU, or EU citizens newly moving to the UK, are in principle governed by national law (partly harmonised by the EU, on the EU side).

However, the #BrexitDeal contains some provisions on visas for service providers.

The #BrexitDeal also refers to the matching unilateral decisions of the EU and UK to waive a visa requirement for short tourist visits. Analysis of the EU law on that issue here:

UK citizens resident in the EU on the basis of the withdrawal agreement (or who move to EU in future) should be covered by the EU law on long-term resident non-EU citizens, which provides for a limited form of mobility between Member States. Analysis here:

Dear fellow musicians, performers, technicians etc. Here’s a thread about how our lives are going to change re touring/working in the EU in 50 days time. Think of it as a kind of Bad News Advent calendar. Here goes 1/

First things first, you’ll need a passport with at least 6 months left on it. And you’ll need full travel/third party/health insurance, since if you get ill or have an accident every penny of your care will have to be paid for 2/

To work or do a gig you’re going to need a work visa, just like you do for the USA. But here’s the thing. Work permits & visas and the conditions attached are a matter not for the EU but for the member states themselves 3/

Yes, every member state controls who comes in and who doesn’t and what the rules will be for work and residency. It’s almost as if the Brexiters have been lying about this ALL ALONG. EU members CONTROL THEIR OWN BORDERS 4/

So you’ll need to get a work permit for every country you’re intending to work or gig in and the rules are often different, as are the rules on eg taxation of that work (eg Spain has a withholding tax, France does not) 5/

This is the second time in one week that I have to engage with something written by a British academic on their assessment of Brexit & Ireland. In this case @HelenHet20 in @NewStatesman 🧵

1. @HelenHet20 Europe’s vaccine crisis has revealed the true nature of the EU?? Ireland has been a member state since 1973, has had more refs on EU topics than any other country & thus its political & administrative elite knows & understands EU @BrigidLaffan

2. Said elite & electorate never idealised EU-small states are acutely aware of limits of their power & deploy capacity with care-the Swedes coined the term smart states. Small states understand they have to be smart. @BrigidLaffan

3. Since 24th of June 2016 Ireland has been shown unstinting solidarity from 26 EU states & EU institutions. During this time, its nearest neighbour tried to power it off the diplomatic pitch & kept thinking that It could peel Ireland off from EU solidarity. @BrigidLaffan

4. On the vaccine debacle & it was one the lesson the Irish will take is that having a seat at the table & voice matters-it took an Irish Taoiseach & Foreign Minister a couple of hours to sort this out. @BrigidLaffan
