Random Weekend Thought (but not really):
If Britain reversed Brexit, they could add £32 billion to the budget every year. Economic problems solved.
(From Wikipedia):
In October 2021, the UK government's Office of Budget Responsibility calculated that Brexit would cost 4% of GDP per annum over the long term. a 4% GDP hit could translate into a £32 billion cost per annum to the UK taxpayer. After rebates, the UK's EU membership fee in 2018 was £13.2 billion.
