asked the Parliamentary Secretary to the Ministry of Defence if he has yet laid down the spheres of responsibility as between the Service Departments for the detection of the launching sites if, and when, guided missiles are directed against this country.

Yes, Sir. This responsibility will rest with the Air Ministry.

Is my hon. Friend aware that I asked this Question on 7th March and 27th June last year of the former Minister of Defence, and that on both occasions I was told that the matter was being examined; and that it will give a sense of confidence that at last a decision is being made?

I am glad that the persistence of my hon. Friend has been rewarded.

Is not the hon. Gentleman aware that it is precisely because there was a careful examination that the Minister is now in a position to give a decision.
