I recommend reading the article, because holy fuck is that whole thing dystopian, but here's who was there:

Those present included representatives of Google, Amazon, Microsoft and Palantir, which works closely with the US military and has contracts with the NHS. IBM and the private prison operator Serco also attended alongside tagging and biometric companies, according to a response to a freedom of information request.

Ah, yes. The very companies that helped install a fascist in the US would be great partners to bring about safety and criminal reform, and they would definitely not inject their fascist ideals into the UK government, eroding and poisoning it over time. Sounds like a brilliant plan! /s
