In Sailing Close to the Wind, Dennis Skinner (I know, cringe socdem but he was there when it happened) mentions how he felt that the miner's strike had been building towards a general strike and then a revolution.

Margret Thatcher did a lot of evil shit to make sure the other unions didn't follow the NUM into strike and considering the other leftist movements of the time, if she'd failed it could've been the start of a larger communist movement in Britain.
