We have five or six deep coal mines left in the UK. It is a disgrace - we import over 20 million tonnes p.a., two thirds of our consumption.

It is what went after the strike that was so destructive - especially 1993 when we closed 31 out of 50 pits. It is bordering on criminal - sheer industrial vandalism by a vindictive, doctrinaire psychopath. Coal miners are the salt of the earth.
It would teach us a lesson if we had another war and had no fuel, but then I suppose we would end up chopping down every single tree in the country to burn.
