EasyStreet,
That takes absolutely no account of how and by whom Special Advisers are employed and paid, to whom they report, and how Government works.
Steve Baker did not want a repeat of his last Ministerial post and was open about that. He did not want to be a junior minister in a department that he saw as being usurped by Michael Gove and his 7 days a week Brexit committee meetings. The rush of announcements, or rather the list of emotional claims to be positive, are simply because the PM wants to leave when he campaigned to leave, 31st Oct, and has about 90 days to do it, all without seeming to weaken his hard line "do or die" leave goal as he knows that would result in him being engulfed in a Brexit Party revival that would be terminal for the Tories.
