I am obviously politically illiterate. Could someone please enlighten me as to how Julia Gillard can announce that Bob Carr has now been chosen as Foreign Minister in her government? He has accepted and publically made an acceptance speech. I was of the opinion that our Federal Government consisted of ELECTED representatives, and unless I have slept longer then I thought, I do not remember this being a fact. I am genuinely puzzled as to how this is so. E1
