Mr. Kilroy-Silk

asked the Secretary of State for the Environment if he has yet received expert medical advice on the possibility of a reaction between carbon monoxide and chlorine producing phosgene gas; and, if so, what was that advice.

Mr. John Silkin

I have not yet received the advice to which my hon. Friend refers.
