Academies have sponsors, who take responsibility. So you can hold them to account to some extent. Do you have a particular issue in mind PurpleDuck?
I think you are thinking of the kind of academies that were originally forced to be academies due to persistent poor performance? The schools which are termed 'academy converter' or something similar (typically grammar schools which changed status about five years ago) were offered the opportunity to become more autonomous as a 'reward' for good
performance. None of those round here have sponsors. I doubt that our local grammars would have considered it much of an honour to be 'allowed' to be taken over by the likes of a creationist carpet salesman, for instance.
