As regards the first part of the Question I would refer my hon. Friend to the answer I gave to my hon. Friend the Member for Neath (Mr. D. J. Williams), on 15th April. As regards the second part, all ex-miners who are not obviously unfit and who are willing to return to coalmining employment are submitted by my local offices to the National Coal Board. The Board are responsible for resolving any doubts as to their medical fitness.
