Two excellent questions at the end of a very sensible thread summarising the post-Brexit UK FP debate. My own take at attempting to offer an answer - ahead of the IR is as follow:

Ok, here's my first bash at how I think UK-EU fisheries will be managed in future now we have the agreement

It’s quite complicated in parts, so would appreciate any corrections…

@StevePeers @BD_Stew @AntonSpisak (& others)

1) QUOTAS: For the next 5.5 years (until end-June 2026), each side’s quotas are set out in the agreement

This amounts to a 25% value reduction for the EU gradually over this period

2) These quotas shares set a new baseline for 2026, but they will be up for negotiation from thereon

3) CATCH LEVELS: However, they will still both need to negotiate overall allowed catch levels for each year, starting in 2021

By 31 Jan, a schedule must be agreed for talks, culminating in final agreement by 10 December (this fits in with the internal EU fisheries negotiation)

4) PROVISIONAL ACCESS: If there’s no agreement by 20 December, each side will apply a provisional allowable catch level for 1 January, defined by the International Council for the Exploration of the Sea based on scientific recommendations

I've been tweeting a lot about UK #OverseasTerritories not being part of the #Brexit deal and a bit more has emerged ...

#Falklands MLA @teslynbark has answered a q about #Brexit and the #Falklands on fb - highlights:

1 Original UK EU mandate didn't include OTs except for Gibraltar.

2 In May, EU said they didn't have a mandate to negotiate for their OTs and wouldn't negotiate on UK OT issues.

(2 possibly explains what @BorisJohnson said about EU "intransigence" in his Christmas message to the #Falklands, but wasn't mentioned when he replied to a pmq from @DerekTwiggMP earlier in the month)

3 @teslynbark says that @falklandsgov held that the new spirit of negotiations that evolved through the year gave space for #Falklands interests to be raised in #BrexitDeal talks and asking for detail on how they were raised by UK Government ...

4 @teslynbark says future negotiations with the EU aren't held to the same mandate as before so @falklandsgov to keep pushing to have #Falklands trade concerns raised

Ten days in and it seems the government's post-Brexit economic policy is to ignore reality, priority and choice, and just claim with no evidence that everything is going to be great. This, needless to say, is dangerous territory. Exhibit 1... 1/

Here's a good example of what is currently passing for UK economic policy. The theory the UK can be 'nimble' in regulations has been present since 2016. In 5 years nobody has found the detail. We presume others might have a similar idea. And trade needs regulations to align 2/

There will of course always be someone to blame. Usually the EU. Because they do indeed want to compete with the UK. This is not exactly surprising. A vague UK idea versus the bigger next door market (or indeed a big one over the pond). Who's going to win? 3/

Next, 'Global Britain' and specifically the Liz Truss speech in the Commons yesterday. To summarise, we are going to do trade deals on everything with everyone while still protecting UK industry and poor countries. Yup, more warm words and no priorities.

Useful example here. The long running EU-US trade battle over food, one claiming to be about quality, the other science. The UK solution. We'll do both! Fabulous, why did nobody think of this before? Unless they did, and found they still had to choose. Note other warm words 5/

1/ Brexit politics is built on fear. Frightened people tend to seek security in the tribe. Once that tribe might have been the Labour movement, but now in a fragmented post-industrial society it is the nation. Tribal identification is emotional, not rational.

2/ A tribe that feels under threat wants to control its borders, and who enters into its territory. It demands loyalty and solidarity, and its prime virtue is self-sacrifice - economic arguments won't persuade tribalists. Its members want to feel it is strong and powerful.

3/ Tribalism at a time of crisis is intolerant of dissent. The tribe must pull together against its enemies. Dissent and questioning cause division and disrupt the collective effort. Criticism is seen as treason. The Brexit right have ruthlessly exploited tribal psychology.

4/ To understand Brexit politics it is necessary to understand that the working and middle classes are dead as coherent political forces and that frightened and insecure people are now clinging to the only available powerful tribe, the nation-tribe.

5/ The Brexit right understands and ruthlessly exploits basic social emotions. In contrast the centre and centre-left mostly can see no further than the blinkered logic of rational individualism, from which perspective everything else is irrational and incomprehensible.

Small business in particular struggling with new Brexit red tape. Entirely predictable, and a function of a world trade system distorted against smaller traders. Stay with me a short while as Brexit threadmeister and story author @pmdfoster may say... 1/

The nub of the issue is the extra costs for most exports, whether this is paperwork or meeting different regulatory requirements. A fixed cost per exported load inevitably adds a higher percentage cost to small than larger business... and they may lack expertise. 2/

You'll note that in the EU, with virtually no paperwork or differing regulations, the costs of exports are similar for smaller and large companies - though even there there is a big company bias, because who can afford to lobby for friendly regulations? 3/

The same unfortunately typically applies to trade deals. If you are Nissan and threaten to leave the country without the right deal you have more clout than a small cheesemaker. As we see. But is it just the EU that is over-bureaucratic? Sadly not... 4/

One of the best UK business groups on trade policy @BritAmBusiness (and yes you can quote me @EmanueAdam) has a new report out on a UK-US trade deal and SMEs. It shows opportunities. But unfortunately problems unlikely to be solved. 5/
