£37Bn over 2 YEARS is what they have budgeted. Sounds like you have been reading fake news posts from the lefties on Face Ache?
There is £22Bn budgeted for FY20/21 and £15Bn for FY21/22. Sounds a lot, but that is a test and trace system for 68,000,000 people, which equates to £323 each. That is enough for just 3-4 COVID tests per person, so it is hardly the Government “pissing away” money. Don’t forget that out of that came 18,000 contact tracers that must have worked at least 100 days over the past year - at minimum wage of around £9 an hour then for an 8 hour day then each one is costing £72, so over 100 days that is £7,200 each. Multiply by 18,000 and that is roughly £130M alone.
If you think you can do such a Herculean effort any cheaper than £323 per head per year, then crack on! I digress...
