This is in the same vein of Politics in Space as the time I wrote Josh Lyman of The West Wing being Princess Leia Organa's political advisor because she'd inherited him from her father,
Matt Santos Jimmy Smits Bail Organa, and then
they observed Space Passover.
Malcolm Tucker of The Thick of It (link is very sweary) deserves someone he can really look up to (metaphorically) and cuss out (effectively).
I propose
Chrisjen Avasarala of the Expanse (link is very sweary and also spoilery), who can give as good as she gets in the cussin' department. Malcolm can't physically look up to her, as she is a tiny Indian (subcontinent) grandmother who dresses fabulously. That won't stop her from kicking his ass.
I'm not sure he'd approve of her tactics, but he's on Team Earth all the way, unless one takes Peter Capaldi's legginess and runs with it to the wonderful world of Malcolm Tucker, Belter, sasa?
I am in the position of having studied English, Spanish, French, German, and Mandarin to the point of being able to mostly follow Belter Creole in audiobook form, where there are no footnotes to be had nor glossaries. Hell if that means I can write it, let alone write Malcolm Tucker Swearing in it, but now I want to try.
Kindly remind me that only about one other person on Earth, Mars, or in the Belt or Jovian system would understand this goddamn story, so it's not worth the effort, because I am very tempted. Unless of course it sounds like fun to you, in which case, can I get a beta offer?
