Your 4999 [to] Dignam  was telegraphed to him through the Dominion Office and the United Kingdom Representative Dublin, for reasons of cypher security.
After passing on the message the Dominion Office Representative told us informally and confidentially their concern that furnishing of letter of accreditation to Dignam by the Commonwealth Government at the request of the Eire Government might have constitutional significance affecting the United Kingdom and other Dominion Governments, and they asked us to mention this to you.
The position was, that hitherto, neither the United Kingdom Representative in Dublin, nor the Canadian High Commissioner in Dublin (so far as known to the Dominions Office) had presented an accrediting letter at the formal reception ceremony. This was the procedure which was applicable to Ministers of Foreign Countries, and was not appropriate for the British Commonwealth representative in Dublin or in other Commonwealth countries. The desire of the Eire Government was to represent themselves as a country external to the British Commonwealth and they accordingly sought every opportunity to give British Commonwealth representatives in Dublin the appearance of Foreign Ministers.
The United Kingdom Government hoped that Australia would follow British Commonwealth precedents and would not allow herself to be manoeuvered on the occasion of the appointment of the Australian High Commissioner in Dublin, into a step which would be embarrassing to other Commonwealth countries.
