When searching for images of "Tristan Osborne MP", two unrelated individuals appear. The first is George Osborne — a former MP and Chancellor who shares a last name. The second is Tristan Tate — one of the Tate brothers who shares little in common with the MP in question other than a first name.
Neither, and especially the latter, should show up in search results. Kagi should realise that a search for "Tristan Osborne MP" (I did not use quotes in the search) does not relate to George Osborne nor Tristan Tate. Screen recordings below, with Google as a reference point.
