The point is Apple and Google did most of the heavy lifting, but the Tory government was too arrogant, stupid or corrupt to initially go with that and wasted £bns of our money in some ridiculous alternative defined by the clueless Dido Harding and the tax-siphoning Serco. They should have started with the globally available iOS and Android infrastructure and used existing local and national NHS and social work networks to trace rather than, in typical Tory fashion, duplicating state functionality via their mates. I don’t know the exact tax/borrowing figure they have squandered on this white elephant, but it is very clearly tens of £bns over budget and looks to have been remarkably ineffective so far. It is a textbook example of Tory ‘privatise the profits, nationalise the losses’ strategy. If we had any credible opposition the Tories would lose the next election on this alone.
