Yes, the miners deserve congratulations on their increased productivity, but is the right hon. Gentleman aware that a crisis of confidence is emerging in the mining industry? He will be aware that on Saturday the Fraser of Allender institute said that 4,000 mining jobs in Scotland would go west, with a total of 8,000 as a consequence. Does the right hon. Gentleman not realise that such stories will affect productivity and that the message in the mining industry will be that the harder one works the more pit closures and redundancies there will be?
