HC Deb 16 March 1910 vol 15 c351
Mr. PATRICK WHITE (for Mr. Nolan)

asked whether the privilege of wearing shamrock on St. Patrick's Day may be extended to postmen, as it was to certain battalions of soldiers?

Mr. HERBERT SAMUEL

No objection has ever been raised to postmen wearing shamrock on St. Patrick's Day, so far as I am aware, and I am informed that many of them do so.
