asked the Minister of Fuel and Power what was the average output per person employed, surface and underground, at the Point of Ayr collieries over the last six months; and what was the average output per person employed, surface and underground, in the whole regional area concerned?

I must refer my hon. Friend to the reply I gave to a Question by the hon. Member for Heywood and Radcliffe (Mr. Wootton-Davies) on 6th April. It is clearly not in the public interest to give figures relating to individual pits.
