I honestly looked hard at the graph in the link below showing total GDP and I just can't see it, sorry. If you are saying the statistics are false then Google it and prove they're wrong. I can provide a ton of them that show that Brexit plainly hasn't had a huge effect, and definitely not armageddon as was predicted by the 'experts'.
Remember that COVID cost us £300-£400bn or about 10% of GDP which we've recovered but this is clearly visible in the data for 2020. I can even see the Ukraine war in 2022 which had a flattening effect. Apparently Brexit has cost us £150-£200bn and yet it's totally invisible? Why has Brexit been a disaster and yet it's totally invisible in the statistics?
The real world data proves that we're not suffering greatly from Brexit, the vast majority of people won't have even noticed albeit except for some adaptation and nuances. Largely otherwise we're suffering just as Europe is suffering from a very difficult environment caused by successive impactful global events and that's it.
The Ukraine war has cost you personally infinitely more than Brexit has. So are you all now going to argue that we should immediately and urgently find a solution with Russia? No, nobody is even arsed. Some even support further military involvement in Ukraine and that includes the EU but at what cost? Against a nuclear armed country! It's mad.
