It was a documentary/clip/interview about 2 elderly upper class British women living together. One was a fascist and one was a communist. They had split the house down the middle and one half was covered with swastikas, the other half with hammers and sickles.
It would have been filmed sometime in the 60s, 70s, or 80s.
They spoke a lot like the Mitford sisters, or other very, very upper-class and old-fashioned people (but were not the Mitford sisters). Thanks!
It doesn’t fit your timeframe but the TV series, Bellamy’s People (2010) in S01E01 has what you have described.
The Combe sisters in it were based on the real life Mitford sisters.
