MINISTERS must open the gates of the "secret garden" of school funding to expose "corrupt practices", NASUWT leader Chris Keates said today.

Speaking at the teachers' union's annual conference, Ms Keates accused ministers of having "no interest" in whether money allocated to schools and colleges was being wisely spent.

Delegates at the conference called for substantial year-on-year increases to per pupil funding — but have also backed a tougher transparency regime around school.
