£30b would be better spent on Brexit or not at all
£30b is like £1000 per taxpayer, which would pay for several years of complimentary broadband per household. The last thing we should be doing is committing the taxpayer to non-essential luxuries like FTTP and HS2/ HS3, when we have the HUGE known and unknown costs of transitioning our economy post Brexit. Let the market decide: let people pay the true cost of FTTP / HS2 / HS3 if they think they need it.
With no EU trade deal, business conditions will change significantly, with both new opportunities and many unviable businesses closing. LOTS of investment will be needed to survive the economic shock. Please prioritise taxpayers money for that, rather than wasting it on services most people don't need!!
