HC Deb 07 March 1944 vol 397 c1892W
Sir R. Tasker

asked the Postmaster-General why all letters addressed to persons in Northern Ireland must be enclosed in a new envelope; and why instructions have been issued to censors to return all letters sent to Northern Ireland if an economy label is used.

Mr. Bracken

I have been asked to reply. If used envelopes were not forbidden it would require a large number of extra examiners to ensure that messages are not concealed underneath the gummed labels. The prohibition is contained in the Control of Communications Order (No. 1), 1941, dated 18th March, 1941.
