Paying tariffs on just about everything and all exports to our larger market subject to punitive levies. Yeah, great idea when the economy (and many people's personal finances) is on its knees
No one planned for Covid, so to be fair up until January, no one had an expectation of the world economy being in the toilet. Most people who voted for and supported Brexit, were OK with looking to negotiate a fair trade deal with the EU. Even with the expectation that the EU would milk it a bit and perhaps get a little more than they are worth. Many also ironically give a little Gallic shrug to that potential outcome, some might even throw in a friendly “Bof”.
The reality is that both the UK and the EU member nations, are on a level playing field of the costing of Covid. But we are only having to sort one nation out. The EU not so much, and arrsing about sorting out Tariffs and Trade Agreements are as old as trade itself.
Would a decent trade agreement suit both our nation and the EU Institution, certainly but there is a element of they have more to lose, since the member states might get the hump losing a lucrative market place. A simple example, I can eat and enjoy Somerset Brie as easily as anything from France.
