I’ve just watched a 3 part drama called A Very British Coup which, as it was made in 1988, I was a bit young for the first time around [this is not the documentary of the same name about the royal abdication].
The dramas were based on the book of the same name [which apparently has a very different ending but I haven’t read it] written by Chris Mullin MP.
It’s fairly interesting and well done and I would suggest you give it a look.
The basic idea is that a genuine left-wing government is elected in the UK. There is obviously extreme media and establishment hostility toward the incumbents but force of personality and a gift with one-line responses carries the day.
The left-wing government sets about making social reforms and disarming Britain’s nuclear capability and so on. As they do this they are impeded at every step by almost everyone in the establishment. Those in high places that try to help them with their reforms are eliminated in one way or another.
There is the feeling of watching a car crash in slow-motion as you watch this because you know it won’t come to a good end.
