§ Mr. Rooker
asked the Secretary of State for Energy if he will list those topics on which it is not his practice to answer parliamentary questions; and if he will list any changes in the practice of his Department since 3 May.
§ Mr. David Howell
It is not possible to provide a definitive and exhaustive list of questions which I might exceptionally decline to answer on grounds other than cost. Each question will continue to be considered on its merits but, by way of illustration, I would decline to answer where confidential, commercial, or security information arises; and on matters which are the responsibility of public bodies.
