HC Deb 25 November 1970 vol 807 c136W
61. Mr. Ashton

asked the Secretary of State for the Environment what estimate he has made of the number of building trade employees at present working on labour-only sub-contracting.

Mr. Amery

None. Statistics on construction industry employees are analysed by the type of work undertaken by their employers, but there is no breakdown between employees of contractors who supply only labour and employees of contractors who also supply materials.
