asked the Secretary of State for Energy what are the current production costs of coal per tonne (a) in the United Kingdom, (b) in Yorkshire and the East Midlands, (c) in Wales and (d) in Scotland; and what he estimates to be the production costs of Selby and Belvoir.

Schedule 8 on pages 58–59 of the National Coal Board's report and accounts 1978–79 sets out the cost of coal production on an Area basis. Estimates of future production costs, such as at the new mines of Selby and North-East Leicester are matters for the board.
