Dokuz Eylül University’s Faculty of Law refused to give permission for Cem Toker, the former head of Turkey’s Liberal Democrat Party (LDP) to deliver a speech on the upcoming presidential referendum.

“They did not let us talk even though we have mere 0.06 percent electoral vote,” Toker tweeted on Thursday.

The incident came amid similar cancellations at several other universities.

Istanbul’s Bilgi University also cancelled a speech titled “No to Violence against Women” by independent MP Aylin Nazlıaka on Thursday. The deputy told media that Bilgi rector called Nazlıaka to apologize for the cancellation of the event and said: “There is great pressure on me,” from the government.

Mehmed Özkan, the controversially-appointed rector of Turkey’s prestigious Boğaziçi University cancelled a scheduled speech by Selin Sayek Böke, the spokesperson of the main opposition Republican Peoples’ Party (CHP), this week.

In mid-February, Özkan also cancelled a panel the outspoken government critic, Sera Kadigil who is also a CHP member.
