Cambridge University is introducing an official 'register' for lecturers to declare if they are having sexual relationships with students.

The measure is part of a campaign to crack down on harassment on campus. Starting next week, the university will unveil a policy that will actively discourage relationships.

Lecturers who disclose liaisons with students could be barred from teaching the students or giving them references.

It comes after alumni claimed they were sexually assaulted by their tutors at the world-leading university in the 80s and 90s.

Called Breaking the Silence, the online guide advises that ‘personal relationships between students and staff should be avoided’.

But if such relationships do exist, they say academics should disclose the relationship in an email to human resources or by talking to their head of department.

Staff can ‘reorganise’ the pair’s schedules to minimise any contact. In some situations, the student and tutor could be banned from seeing each other in a professional capacity to make sure they do not receive any preferential treatment.

Students will be able to take part in the Good Lad Initiative workshops, which tackle the macho culture at university.

In a statement, Cambridge University said: ‘There is no place for any form of harassment or sexual misconduct at the University of Cambridge.

‘All members of the university community have an individual and a collective responsibility to ensure that their professional relationships are sensitive to the imbalances of power that exist within any organisation.’
