§ 60. Mr. Bellenger
asked the Postmaster-General whether he is aware that conversation in public telephone boxes can be 672 overheard by users of contiguous telephone boxes; and whether he has any proposals for a better system of insulation, so that conversations in public telephone boxes can be private and not overheard?
§ Major Tryon
I am sure that the hon. Member will appreciate that when telephone cabinets are arranged in suites, and each of them is properly ventilated, a certain risk of overhearing is inevitable. In cabinets of current design these risks are greatly reduced; and constant research and experiments are in progress with a view to still further improvement.
