HC Deb 22 November 1939 vol 353 c1240W
Captain Plugge

asked the Postmaster-General for what reason British mail to Switzerland recently arrived in that country marked as opened by the German censorship; and why this mail was sent to Switzerland via Germany?

Captain Waterhouse

It has not been possible to determine the exact circumstances in which these letters were diverted from their proper course, but my inquiries suggest that they were sent in error to a neutral country and reforwarded with the mails of that country to Switzerland by way of Germany. Instructions have been given to the staff that the greatest care must be exercised to avoid a recurrence of this mistake.
