Already many people in Ilkley are in fact based in London and commute. Perhaps cutting links to London would be an interesting idea? A bit like island ecologies in which new species and environments evolve; Much more creative.
I can see that there may be a benefit in having control from London (managers commuting from Ilkley) and a cheap workforce based out in the regions (like Indian call centres).
I think on balance id like to see more stuff going on in Yorkshire that is unique and independent of London. I suppose if there’s a good rail service I will be able to visit exhibitions and shows without them needing to come to Yorkshire.
