§ 55. Mr. Lipton
asked the Secretary of State for the Environment what action he is taking by the use of modern biodegradable cleaning chemicals and detergents to reduce the pollution of the Thames by effluents from those parts of the Palace of Westminster occupied by the House of Commons.
§ Mr. Channon
Liquid waste at the Palace of Westminster is not discharged into the Thames but into the sewer. Detergents of the highest level of bio-degradability are purchased by my Department for the use of the direct labour force which is chiefly responsible for cleaning the Palace of Westminster.
