Ha Ha "more astute???" do you mean David "i don't need briefing papers" Davis or Dominic "i don't know where Dover is" Raab?
I think its the other way round, the vast majority of the electorate now see Brexit as a mistake, not least on immigration having trebled since Brexit.

Labour have ruled out SM or CU membership.
The deal the Tories negotiated is terrible, 48 hours stuck in Dover, customs checks, huge amounts of paper work, SMEs halting trade with EU, no veterinary agreement, problems with musicians and athletes performing & the new ETIAS system is going to make travel to holiday in Europe extremely long winded.
If the UK wants growth, it will need a far better FTA than we currently have.
