Since 1979, when the Government came to power, coal imports have increased from 4 million tonnes to 19 millions tonnes, an increase of 346 per cent., which has had the effect of wiping out the coal fields of south Wales, damaging our balance of payments, costing the taxpayer £8,500 for every one of the tens of thousands of unemployed miners, and making us dreadfully dependent on foreign supplies. Does the Secretary of State appreciate that that is economic lunacy of the highest order, or is he just plain thick?
