It's been another torrid week at the border - inundated customs agents, goods stuck for days, companies buckling under the paperwork 1/ https://t.co/2A301guhB6 w/ @lizzzburden

New: the European Parliament's announcement that it will not ratify any treaty before the end of December unless the deal is concluded by midnight on Sunday comes amid signals that, despite progress, a deal won't be concluded until early next week.

2/ This is because there are still some formidable hurdles in the way of closure on the level playing field issue, and they haven't even got into fisheries in a big way yet. And both sides say things there are "extremely difficult".

3/ Yesterday there were some signals that a deal could be done by the weekend, but the mood seems to have dipped somewhat.

4/ The EP is saying it wants a "provisional" text from the European Commission "as soon as possible" - not clear if that means even before the midnight deadline

5/ If a deal is not concluded by Sunday night then we are in uncharted waters

One of the root causes of the Govt's Brexit difficulties is that it has overpromised.

We can, it is said, reclaim our sovereignty, with the freedom to make our own rules, and, at the same time, retain many of the advantages of EU membership. 1/14

The reality is that we cannot.

Unless we agree to certain standards and rules (and there is scope to argue about which rules), there will be borders, and checks, and tariffs. 2/

There will always be a relationship between rights (eg tariff free access to EU/UK markets) and responsibilities (eg abiding by level-playing field commitments). 3/

A 'good' outcome for the UK, in the Govt's view, would involve access gains (eg fewer border checks) without corresponding obligations (or with weak, or difficult-to-enforce obligations). 4/

The chances of this sort of 'good' outcome are low. The EU looks likely, in the face of the threats in the Internal Market Bill and now the Finance Bill, to insist on rigorous governance provisions. [Also, such provisions are the foundation of the single market.] 5/

1/ What are the ‘new’ demands the UK says the EU has made in the Brexit talks and are they actually new? There are 3 specific areas of contention that have emerged, one each on state aid rules, the Level Playing Field/Governance, and fish. None of them should be a total surprise.

2/ First, on state aid. The UK says the EU wants the Commission and European Investment Bank to be given carve-outs from the subsidy control provisions in the deal. It says this would create an unfair imbalance, because there would be no similar exemption for British authorities.

3/ This is particularly relevant in light of the bloc's €750bn Coronavirus recovery fund. It has already been delayed by an internal political row, and the EU is keen to ensure that isn't exacerbated by legal disputes with the UK next year. Brussels denies this is anything new.

4/ The Commission is an ex ante regulator, meaning it is called in to pre-authorise state aid spending by EU countries. The EU wants the UK to set up its own independent regulator to approve subsidies in the same way. If it does so, many of the state aid problems will fall away.

5/ LPF/Governance. This is about the 'ratchet clause' which the EU has relabelled as 'equivalence' of standards. It addresses what happens if one side raises its standards on say environmental or labour rules in the future and the other doesn't, creating a competitive imbalance.

Prof Valsamis Mitsilegas tells NI committee that the agreement on JHA is dynamic, as EU values UK inputs, and EU law will evolve over time, and value of system to UK will mean adaptation

Prof Steve Peers of Esssex Uni. Tells NI cttee that deal keeps 3/4 of previous arrangement, missing quarter is SIS II and some other capabilities in data exchange. Says quite a lot has been preserved by two sides, esp compared to no deal situation

Simon Hoare MP - is the deal adequate to challenge of policing NI, and IRL: Dr Gemma Davies (Northumbria law school). Says Data Protection issues v complex, PSNI/AGS co-operation might be better facilitated by specific agreement (not going beyond EU agreement, but clarifying)

Colin Murray tells NI cttee that Norway/Iceland extradition arrangements with EU put in place 10 years ago, now working in ways comparable to EU arrest warrant. Operational issues get easier to fix over time.

Colin Murray says there are break clauses in the TCA, and the police element could break down in a relatively short period (in theory).
