It's utterly bogus. The lion's share (£176bn) of your £380bn comes from, according to your own report - instantly slashing "Working Time Directive, Climate Change and Renewable Package" etc - with £132bn coming from instant FTAs.
The authors are also claiming that their polling data show Brits don't want an extension, whereas their own data show more Brits than not think it beneficial:
Further, the report sings up the benefit of trading on WTO rules (25 mentions in doc) - without a single mention that the WTO is utterly broken, in financial trouble, chief just resigned, US pulling out & with no capacity left to enforce said rules.
What Boris Johnson was *trying* to say (in a hurried way)...
... is that Covid-19 can be detected in wastewater (not water supply), meaning that if you monitor wastewater from all towns, you get a clever early indicator of outbreak & can swoop in local lockdown measures.
Furthermore, saying no ECJ whatsoever is again petulant and not pragmatic.
Look at the EU science programme. If we sign up to be a country whose institutions can receive & distribute money from the EU kitty, who oversees that legally? Clearly the ECJ - the Swiss do it that way.
If you are a coordinator for an EU science project, you receive all the money and you are responsible for managing the budget and distributing to the other (multinational) partner institutions.
If there is any legal/financial dispute between partners, the ECJ sorts it.
“Until now, British drivers have enjoyed access to all EU and EEA countries ... without the need for any extra documentation. But starting next year, UK drivers will need an international driving permit to use their cars in most European countries.” telegraph.co.uk/cars/advice/dr…
“There are three types of IDP, however, and not all are recognised by every country. The two you’ll need for European trips are known as the 1968 Vienna Convention IDP and the 1949 Paris Convention IDP, which last for three years and twelve months respectively.”
“Each version of the IDP costs £5.50, so if you need both you’ll need to pay £11. A 1968 IDP lasts for three years, while the 1949 IDP will need renewing after just one year. Not having an IDP in a country where you need one could land you with a fine.”
I did not say “removes” our capacity - we can of course still work with EU27 - I said “sets back” because: 1) Brexit has an opportunity cost of time, energy & finances 2) undermining environmental protections is the wrong direction.
Furthermore, it’s sending all the wrong signals that we’d do a trade deal with US when they say UK/global climate targets cannot be mentioned in such a deal (see article)
