HC Deb 26 June 1957 vol 572 cc29-30W
47. Mr. Llewellyn

asked the Postmaster-General whether he is satisfied with the working of the electronic random numeral indicating equipment; and if he will make a statement.

Mr. Marples

Yes. It has fulfilled all our expectations both under test and in the first of the monthly prize draws. As an illustration of its randomness, I am circulating in the OFFICIAL REPORT a table which shows how closely the proportion of prizes awarded to each denomination in June corresponded with last November's sales.

Following is the table
