Chaos and instability in Bristol South secondary schools: is no-one being held to account??

What utter chaos and instability we have in some secondary schools in Bristol South. First Hengrove axes GCSE courses after students started them (see here) and now they are closing the sixth form part way through the year ('Anger as sixth form is closed', Bristol Evening Post, 5 March 2008)!! Is no-one going to be held to account for this apalling organisation which is sure to significantly disrupt the education and lives of young people?
