asked the Minister of Labour whether he will institute an inquiry to assess the safety factors arising from the increase, in the building and construction industries, of labour-only organisations.

This is one of the subjects which is being covered in a special investigation into construction accidents which is being carried out by members of Her Majesty's Factory Inspectorate on selected sites in the Midlands, and which I expect to be completed during the autumn of this year. The investigation was planned in agreement with my Joint Advisory Committee on Safety and Health in the Construction Industries and the results will be referred to the Committee for consideration.
