Harold Wilson closed more mines in the 60s than Thatcher did in the 80s. The vast majority of them were worked out.
And they’re wasn’t such opposition to the closures in the 60’s because we were running at pretty much full employment so there was work in other fields for the redundant miners.
Not so in the 80’s. Even after meeting the goals set by Heseltine in production mines were shut - destroying communities in a stroke. So different.
