The top 10 neighbors for Boris Johnson span six distinct subcategories — Athletes, Government Officials, Politicians, Activists, News Publishers, TV Personalities, Authors, Podcasts and Radio, and TV Shows — with no single type dominating and scores compressed into a narrow band from 0.82 down to 0.79.

Similarity here measures how closely two entities' audiences resemble each other in composition. The shape is flat: Gary Lineker leads at 0.82, but Gen Michael Hayden is just a fraction behind at 0.82, and the remaining eight neighbors — Michael McFaul (0.80), Holly Figueroa O'Reilly (0.80), RTÉ News (0.80), Max Boot (0.80), Piers Morgan (0.80), BBC Radio 4 Today (0.80), RealClearPolitics (0.80), and Have I Got News For You (0.79) — are essentially tied. No single neighbor pulls away from the pack.

The subcategory mix is notably cross-kind. Boris Johnson is categorized as a Politician, yet only one other Politician appears in the top 10 — Michael McFaul at 0.80. The remaining nine neighbors are drawn from Journalists, Government Officials, Athletes, Activists, TV Personalities, Authors, News Publishers, Podcasts and Radio, and TV Shows. The presence of Gary Lineker (Athlete) and Have I Got News For You (TV Show) alongside political commentary figures like Gen Michael Hayden and RTÉ News reflects an audience that tracks across British public life broadly, not just the political lane.

The flat, cross-kind structure suggests an audience defined less by partisan or institutional alignment than by a general engagement with news, commentary, and public affairs across formats and nationalities.
