The article is part of the problem. UK politics and the media narratives around it have beeen utterly wrecked by the fight over Brexit and the attempts to give its creators the boot. For example, take this claim: "Investment is down and inflation higher than it would have been inside the European Union." The UK's inflation in the year to November 2022 was 10.7%, compared to 10.1% in the Eurozone. It just doesn't seem at all plausible that the UK would somehow have substantially lower inflation if it were in the EU, based on what countries actually in the EU have experienced, yet it's treated as so obviously true that only lying Brexiters would reject it.

This belief is boosted by the fact the British press only ever compares our inflation with France, which has the lowest inflation in Europe due to substantial nuclear generating capacity and energy subsidies funded through borrowing. Our government was attacked for attempting even a fraction of those energy subsidies to the point they did a U-turn because ultimately the public pays for it, but that downside is ignored when talking about France. They also also have substantially more national debt for obvious reasons... but luckily the UK national debt is usually only compared with Germany's.
