§ 50. Mr. Maddan
asked the Postmaster-General what sizes and weights of envelope will be accepted for general election communications.
§ Mr. Joseph Slater
My right hon. Friend proposes to bring the permissible dimensions for these envelopes into line with the Post Office Preferred range by increasing the minimum from 4 in. x 2¾ in. to 5½ x 3½ in. and the maximum from 9 in. x 4½ in. to 9¼ in. x 4¾ in. Envelopes would need to be oblong with the longer side at least 1.414 times the shorter; preferably they should be made from paper weighing at least 63 grammes per square metre. As now, envelopes and their contents must not exceed 2 oz. in weight.
