HC Deb 17 October 1968 vol 770 c162W
44. Mr. Grimond

asked the Postmaster-General on what principle stamps are issued to commemorate notable anniversaries in British history.

Mr. Joseph Slater

We look for anniversaries of current national and international significance or of wide historical interest and appeal. We aim also to include from time to time events and anniversaries of particular importance to the various countries making up the United Kingdom.
