Brexit

Brexit was, depending on who you ask, was either the worst thing or the best thing ever to heppen to the UK. Whatever the ultimate benefit of the vote, Brexiteers have since become a popular target for the media to mock, notably as ridiculous Strawmen embodying every negative stereotype of the Little Englander. Of course the BBC was the main exponent of this risible propaganda, resulting in massive Cringe for any viewer with an ounce of sense. Of course this aforementioned audience does NOT overlap with the Doctor Who Fandom. Lol.

1. Forsehadowing
The 12th Doctor made a rather unpleasant habit of referencing Brexit and/or Trump during inapproprate moments, ruining many otherwise kino episodes.

2. Ipso Facto
The Bregzit arc proper made its debut in Red Tape. The incarnation of the Doctor who initiated it was played by David Cameron, but after being accused of having sex with a pig (as foreshadowed by Charlie Brooker in Black Mirror) he regenerated out of shame and turned into a woman, who in great irony for the feminist segment of the audience died in under a year, overwhelmed by the mountain of paperwork and negotiations involved.

3. the 14th Doctor
Aha! Finally! Well... You can really tell how Boris Johnsoon took acting cues from Peter Davison in that FUCK ALL HAPPENS. Thank god for the Brexit arc.

In Big Finish
Have no fear, we'll have stories for years! Somehow even more boring than the TV arc. Briggs took advantage of the timey-wimey nature of the program to create two alternate timelines: one where Brexit failed and Cameron remained as the Doctor, the other basically an expansion pack to the TV series detailing fascinating details such as 14's toilet routine, Teresa may's escapades at the swinger's bar, and some interminable parlimanet scenes rendered incomprehnsbile by Slitheens farting.

90% of the regular BF actors were involved in some capacity, if only as foley artists to make the "Dismayed crowd#2" and "Angry Whiny Remainer" effects, repeated ad nauseam throghout the many boxsets (totalling around 57 hours btw)
