I'm not sure why a political party, which is an entity formed to get people elected to public office in one particular country, needs to communicate with heads of state of other countries. I can see an individual legislator or MP getting involved with another country, but not a whole political party. Nonetheless, if such occasion should arise, just about any way will do except an official letter taking a commanding tone instructing the heads of other states as to how they allowed to regard Northern Ireland's position re the EU. Such a letter, if it is appropriate at all, would be appropriately written by Northern Ireland's leader.
Some months ago, Foster was that leader, entitled First Minister. She no longer is First Minister, and that position is vacant. Foster's letters are clearly a statement that she is to be regarded as still the First Minister, or the closest thing to one since the position presently is not filled. Basically, she's pretending she has legal power she no longer has.
