Why Is Nobody Mentioning Brexit?

It has been blamed on the Covid pandemic and Russia's invasion of Ukraine but as they are global economic shocks, the question must be why is Britain's economy doing so much worse than every else's?
The Bank of England governor, Andrew Bailey, has warned inflation is set to be higher for longer here in the UK, and growth in the economy weaker too which agreed with the International Monetary Fund and the Organisation for Economic Co-operation and Development who said that the UK economy is probably weakening rather earlier and somewhat more than others.
Economists are predicting that Britain is heading towards a deeper and longer lasting recession than other European countries due to Sterling falling markedly and UK trade reaching its worst levels in record in the first quarter and interest rates and inflation at an eye watering level.
Undoubtedly the Pandemic and Ukraine does have an impact but the elephant in the room which i don't seem to be hearing mentioned is Brexit, that act of economic suicide which was forecast to hit Britain's GDP by 4% on it's own without any of the other factors.
The British Chambers of Commerce have issued a warning that due to Brexit related trade reduction, supply chain and labour shortages, the Government must review its shortage occupation list to allow more Foreign worker in to work here amid damaging staff shortages.
The Labour Party opposition seem afraid to mention Brexit, the division between Leavers and Remainers is still raw, but someone needs to shout loud that due to the madness of the 2016 vote for Brexit, we are inflicting upon ourselves real economic harm and will continue to do so until someone has the guts to stand up to the little Englander's, point out exactly what damage we are doing for very little reward and go back to the EU and apologise very, very hard and ask if we can return to their market, pretty please .
