Graffiti demanding the resignation of the president of Imperial College London over bullying allegations has appeared on walls outside of her residence as the chair of the parliamentary education committee added his voice to calls for the release of a report into the claims. Unease has been growing among the student and the wider academic community after the university’s authorities refused to publish the findings of an investigation into “a dysfunctional culture and alleged bullying”, leading to further accusations of a cover-up. Allegations against Imperial’s “most senior staff” were followed by a disciplinary process involving some of the individuals who were subject to whistleblowing allegations, the university’s authorities said. While the content of the report compiled by Jane McNeill QC has not been made public, the disciplinary panel constituted by the university council has decided that the dismissal of Imperial’s president, Alice Gast, was not warranted. Apologies have been issued by Gast and Imperial’s chief financial officer, Muir Sanderson. The university has declined to say what they apologised for. Gast receives £554,000 a year in pay and benefits as Imperial’s president, a role she has likened to being its “chief executive”. The Conservative MP Robert Halfon, who chairs of theeducation select committee, said the report should be published for transparency, “so that all those affected can be assured that proper action is being taken”. A university spokesperson for Sanderson said the CFO was “fully supportive of the changes that have been put in place as a result of this process, and … has offered full apologies to those people who were affected by his conduct”. Asked whether “conduct” was a reference to bullying, the spokesperson said: “We cannot clarify this as the report remains confidential.” One of the whistleblowers who gave evidence to the investigation said members of staff were still “living in fear” of Gast and Sanderson and felt “let down” by the university and its governing council. A spokesperson for Imperial said: “As the appointment of an independent QC and disciplinary panel in this case shows, we treat any reports of bullying with the utmost seriousness, and have processes in place to provide support and investigate any allegation thoroughly, whatever the seniority of those involved.” Student leaders at Imperial have expressed disappointment at the authorities for refusing to publish the findings in a redacted form to protect the identities of those who gave evidence. They were responding to a letter from John Allan, the council’s chair, and Prof Ian Walmsley, the university’s provost, which said the allegations “concerned a dysfunctional culture and alleged bullying of some staff members”. “Our policy is clear that zero tolerance means any complaints must not be ignored and will be thoroughly investigated. That’s exactly what happened,” the letter said. But a response from Abhijay Sood, the president of Imperial College’s student union, and other union trustees, said: “To us, zero tolerance implies severe consequences. At the most senior level, it is hard to imagine what this could entail other than removal from the organisation. “We are concerned that this dysfunction may now grow, as the perception of a light touch response might prejudice the ability of staff members to properly manage similar disciplinary cases when more junior staff members are accused of similar indiscretions.”
