The rector of Naples Suor Orsola Benincasa university is under investigation for allegedly helping the son of a former minister get a research position at the institute. The news came two days after seven university teachers were arrested by Florence finance police in relation to a probe into the alleged rigging of exams to qualify as lecturers. Another 22 people have been barred from holding academic positions for 12 months in relation to the probe and 59 people are under investigation in total. The probe was triggered by an alleged attempt by some teachers to persuade a researcher who was a candidate in an exam to qualify as a tax-law teacher to withdraw the bid in favour of a less qualified candidate.
