§ Mr. Swinglerasked the Minister of Housing and Local Government and Minister for Welsh Affairs what has been the result of his further study into the question of the compulsory filling of marl-holes.
§ Sir K. JosephMy right hon. Friend has given careful thought to this question and, as the hon. Gentleman is aware, he is still of the opinion that there is no need for further general legislation. The local authorities have various statutory powers under which they can acquire and reclaim derelict workings of this kind, and more can be done by stimulating co-operation between owners or derelict workings and owners of land containing supplies of filling material.
