Uh... Disagree.
> On January 11, 2024, the London Mayor's Office released the "Mayor highlights Brexit damage to London economy". The release cites the independent report by Cambridge Econometrics that London has almost 300,000 fewer jobs, and nationwide two million fewer jobs as a direct consequence of Brexit. Brexit is recognized as a key contributor to the 2023 cost-of-living crisis with the average citizen being nearly £2,000 worse off, and the average Londoner nearly £3,400 worse off, in 2023 as a result of Brexit. In addition, UK real Gross Value Added was approximately £140bn less in 2023 than it would have been had the UK remained in the Single Market.[0]
The whole page paints a picture which is far from "no measurable negative impact". While it's contrasted with some areas suffering and others benefiting, it's hard to have an overall picture that looks either good or bad, but it's far from being overly positive. And this is just on the economic topic, there's another whole hoist of topics which have negative outlooks such as security, politics (i.e. with the Ireland controversy and how difficult this situation is), etc.
