Problem
Read the following section of a speech delivered on December 11, 1936 by British King Edward VIII in which he abdicated (formally relinquished) his throne:
Ever since I was prince of Wales, and later on when I occupied the throne, I have been treated with the greatest kindness by all classes of the people wherever I have lived or journeyed throughout the empire. For that I am very grateful.
I now quit altogether public affairs, and I lay down my burden. It may be some time before I return to my native land, but I shall always follow the fortunes of the British race and empire with profound interest, and if at any time in the future I can be found of service to His Majesty in a private station, I shall not fail.
What are the coordinating and subordinating conjunctions in this section?
