Does anyone know anything at all about the UK coal mining industry and the overall decline?

How many coal mines were actually closed under the Labour Government (mainly Harold Wilson) ?

How many coal mines were actually closed under the Conservative Government (Margaret Thatcher) ?

I'm not defending or attacking anyone just want to establish facts that are plainly ignored.

Why do we only hear that Margaret Thatcher destroyed coal mines and the associated mining communities when the facts show a hugely different story?
