If they are not here, all three of them, these hearings won’t end," he said.Ngutshana informed the hearings that Mahlangu had indicated she would be willing to testify at the hearings, but only after the completion of her examinations, believed to be in the next few weeks.But a quick look at the London School of Economics indicates the university only has examinations in January.During lunchtime on Tuesday, a group of activists demonstrated outside the London School of Economics to put pressure on the university and Mahlangu to return to South Africa as soon as possible to testify.Protesting in solidarity #LifeEsidimeni Qedani Mahlangu responsible for death of 141+ mental health patients in SA studying at LSE pic.twitter.com/0ODDWPPPX5— Tabitha Ha (@Tabithaha) October 24, 2017Organiser Diarmaid McDonald told News24 the group intended on demanding that Mahlangu takes responsibility."We really think she should be on the next plane home and face the families of the 140-odd patients who lost their lives," McDonald said."She herself needs to take responsibility and be accountable for her role in [the Life Esidimeni tragedy]," he said.McDonald said the group felt the London School of Economics should be aware of Mahlangu being a student at the university and her actions that led to the deaths of Life Esidimeni patients.Meanwhile in a statement the ANC in Gauteng said it has been in discussion with Mahlangu on her availability to appear before the arbitration."She indicated that she does not have any problem to appear but was not on the list of witnesses.
