The Oxford physicist mentioned in the article may well be Joy Christian, who has submitted numerous articles to Arxiv giving what he claims to be a violation of Bell inequalities using Clifford algebras. You can find them just by searching Arxiv for his name. I spent some time reading these articles and the various refutations - and refutations of refutations - when I was a grad student, as I wanted to nail down where either he or Bell was fundamentally wrong. I never succeeded, but since Bell's proof was much simpler and understandable, and involved more elementary objects, and had been scrutinised for much longer without any serious flaws forthcoming, whereas Christian's proofs appeared to have some issues under debate, I came away thinking it likely that Christian was wrong. Disappointing that I couldn't find the "central" flaw, if there was one. Sad that a talented scientist should spend so much of their career simply alienating themselves from the community in this way.
