Not an expert but Oracle was a company providing software to a local authority, once you end that contract, you can remove data from the systems, I think with AI once you hand over the data to AI (esp as 5/7 are based in the US) then don't we lose control of that data.
I would hope at least that any systems are going to be based in the UK as in we have our own servers running software that uses specific AI algorithms to analyse the data (if that is the use case).
