We generally don’t exercise diplomatic immunity....with close allies. It’s designed for relations with more hostile countries—who, for example, would falsely charge our diplomats, in a tit-for-tat way, for a similar crime. I’ve never heard of diplomatic immunity being used against the UK.
Besides this being the UK, a military intelligence officer...is not, by definition, a “diplomat,” and certainly not his wife.
