Of course we know that there can be exceptions. Plus, she has connections. She is pretty closely related to the ONE person, unequivocally, that can grant British citizenship by a mere pronouncement. I would bet the Queen is not aware. She must have assumed that it was a done deal long time ago.
She just went on a Royal Visit to Africa representing the Queen. It is NOT right that she did that not as a citizen. She met with Heads of State. There was a potential for security violations.
As far as I can see they haven’t started taping the 2016 edition, i.e., Season 7, as yet. Given the tent and the verdancy that surrounds it the tapings are most likely done in June or July. So still a few months left. Season 6 (2015) started airing in mid-August. So that is probably when we can start expecting season 7 this year — on YouTube. i.e., around August 2016. I will, of course, keep you posted.
