Your correspondent makes allegations that, if they are true, reflect badly on his/her practice as an examiner and bring universities in general into disrepute. Why does your correspondent hide his/her identity? As an internal and external examiner with many years' experience, I recognise none of the scenarios outlined in the letter. I do not think The Times Higher should publish anonymous letters. Ironically, I can't sign this letter from my place of work because my institution (Stirling University) forbids us writing to the press from our work address.
