asked the Home Secretary whether the new air-raid warning regulations are operating satisfactorily in all respects; and whether he is aware that in recent air-raids the time between the warning and gunfire or bomb-dropping is insufficient in some instances to enable persons to take cover in safety?

I would refer my hon. Friend to the answer which I gave to my hon. Friend the Member for Durham (Mr. Ritson) on 8th July. The new system is not yet in operation as the preparatory work is not completed.
