asked the Secretary of State for the Environment whether, pursuant to his reply to the hon. Member for Basildon of 18 May, he will list in the Official Report the titles of all those reports that were commissioned by his Department in 1980 and 1981, respectively.

[pursuant to his answer, 24 May 1982 c. 255]: A wide range of reports and studies are commissioned and carried out every year by Ministers and officials in my Department. There is no need for a central record, and a list of titles could not be produced without disproportionate cost. Records are, of course, kept for the specific research programmes: in 1979–80 work was carried out on 312 projects, costing £19·9 million; and in 1980–81 there were 265 projects, costing £25·5 million.
