OK, to summarise. What we didn't necessarily know about Brexit in 2016, but we are fairly sure about now. (Most projects would expect you do your due diligence - and have a project plan, and clear objectives) BEFORE starting work).

1. There will be a medium-term shortage of medical isotopes (diagnostic and therapeutic). Medicines, especially temperature-sensitive ones like insulin, hormones, and targeted immunotherapy, will be in short supply. People could have their health put at risk, and some may die.

2. There will be shortages of food, especially fresh foods such as salads, vegetables, fruit and milk. The UK has not been self-sufficient in food since 1850. Tight-budget items such as school meals, hospital and care home food will suffer most.

3. British companies will find it harder to export due to the sinking £ and to new tariffs which the EU must impose to be compliant with WTO rules. International companies that can move abroad may do so, cutting UK jobs. Those that can't move, may go under.

4. British companies importing raw materials will suffer from inflation, which they will pass on to consumers. If their offer is "discretionary" e.g. cafes, florists - things consumers can cut back on - their businesses will suffer and they may have to close or to lay off staff.

5. Farmers, especially those on marginal hill farms, will suffer not only from high tariffs but from loss of EU subsidies. Roughly half of farms are predicted to fail under a No Deal Brexit. And UK fishermen will lose their biggest export market.

6. We will lose European Structural Development and Social Fund grants to our poorest regions.

7. We will lose Horizon 20/20 and successor funding for collaborative scientific projects. Scientists are mobile, they will get work permits overseas - there will be a brain drain.

8. Fuel refineries may have to close, again due to our export countries imposing tariffs on UK fuel. This will leave us dependent on foreign fuel from lovely friendly countries, like Russia, for example. Oh, and our services industry, 80% of the economy, is already affected.

9. Our EU27 friends, family and work colleagues may not be able to stay in this country, where they bring up their British kids, work in our schools, hospitals and companies, pay their taxes, live their lives. The stress on them is evil. EU countries are watching us with horror.

10. We will break our agreed responsibilities under the Good Friday Agreement, a solemn peace treaty lodged at the United Nations. Borders will have to go up across the island of Ireland, identities will be threatened, a rise in violence and death is likely.

11. Northern Ireland and Scotland will feel rather less minded to stay in the United Kingdom. and who can blame them?

12. Our neighbours in the Republic of Ireland will have their economy shafted almost as badly as ours, although the EU will no doubt try to increase their imports of Irish goods. You might think that previous British governments have done enough harm here, but no.

13. British people will lose hard-won rights and freedoms - FOM, but also a lot of our rights as consumers and workers, and our rights to a clean, unpolluted environment. Unscrupulous governments (we already have one) will have fun with that.

14. Austerity will have to be maintained for generations. With a shrunken economy, permanently low wages, and fewer protections, we will become the most oppressed population in the developed world. We might even become economic migrants. I hope other countries are kind to us.

15. Britain has lost its reputation for good governance, stable government, tolerance, fair play and being "men of our word". Who will trust us as a trade or political / diplomatic partner? Best leave us to our splendid isolation.

16. But it's all worth it, for "Sovereignty". We give up being an influential member of the world's biggest economic community, where we have a say in policy and strategy, to become dependent on the US, Russia and China, where we partake in their parliamentary... oh, wait...

17. So let's not stop being angry. Let's not stop being outraged. Let's ask our government every day - "WHY ARE WE DOING THIS AGAIN". There is NO good reason for Brexit. #StopBrexit.
