What I think we're about to discover in the UK is that we took seamless borders for granted for 25 years.

Queueing at borders is the global norm. UK politicians of the 1980s were part of a west European effort to remove these, the UK more for trade reasons, other countries that and the symbolism of Europe without borders.

Saying the EU is "imposing" checks is like saying China or the US are doing the same. It isn't exceptional and media failing to challenge this do us a disservice.

Yes you can "speed up" border checks. But that's a long way from eliminating them. https://twitter.com/Scott12Colin/status/1308674546329948160?s=20

Oh, and speeding up border checks requires agreement between the countries concerned. That's a proper deal, not the misleading "Australia-style" terms.

As for the impact of border checks for the UK economy short and long term, inevitable but as yet unknown.

Also, without an EU trade deal the UK has to impose the same checks on goods arriving from the EU as from anywhere else. WTO rules.
