I've been reading rumours about this all over Twitter. My first reaction was that, if true, it's truly shocking. But is it true? I spent some time yesterday looking for some proof and I couldn't find anything definitive. As far as I can tell, the contract was outsourced to Fujitsu. The allegation is that it was sub-contracted to Infosys, in which Sunak's wife has shares (her father founded the company), but I'm not sure that's true. Certainly, Infosys has done this kind of work in the past, but I don't know if there's any proof it was involved in the UK alarm. I stand to be corrected, if there's any proof, but until then, it's just a rumour as far as I can tell.
