The purpose is to invite Prince Harry to voluntarily ask The Queen to put his royal style, titles and rank into abeyance, thereby freeing him from the diplomatic, political and constitutional constraints that are an inevitable part of royal rank, and further freeing him from the constitutional conflicts which his beliefs are creating, with all their  implications at home and abroad, in particular in the United Kingdom and the United States of America, where his articulated beliefs are in open conflict with the accepted tenets of  both the United Kingdom and American Constitutions.  As a purely private citizen, with no royal rank, style or title, he will be able to indulge his personal beliefs, as is the right of all private citizens, without the consequential possibility of damaging the institution of the Monarchy or  relations between Friendly Powers, and will be free to articulate beliefs, no matter how objectionable, without the fallout  that is otherwise inevitable as long as he possesses royal status.  His invitation to The Sovereign, being of his own accord,  will resolve conflicts that would otherwise be inevitable, and will permit him to enjoy the credit of having put both national and international interests above his own, personal ones, in the process gaining him respect that he otherwise will not enjoy.
