Unrelated to the topic in hand, there was (and probably still is) an interesting blog post on Fish's website, maybe 10 years old, about the costs of touring (generally, not a Brexit related thing), costs, who takes what, ways he's found to keep it viable, and how many times he's had to remortgage his home to keep at it, etc. It was a really good read.
Related to the topic, my MP is the culture secretary, a typical party line yes man... I shall of course lean on him, but I know from previous dealings with him that I may as well try to nail water to the ceiling.
