asked the Postmaster-General whether he is satisfied that, in the event of war, there would be sufficient alternative broadcasting stations to maintain a full national broadcast irrespective of the possible destruction of one or more stations; and whether he can give reasonable assurances that existing plans are adequate to prevent the jamming of this service?

It is not in the public interest to say what action His Majesty's Government intend to take in regard to the broadcasting service in the event of war; but I can assure the hon. Member that the matters to which he refers have not been overlooked.

Is the Minister in communication with the Minister for the Co-ordination of Defence on this subject?

The matter is being considered by the Government.
