Kenyan Professor Patrick Lumumba delivers the fifth Onkgopotse Tiro Memorial Lecture at the University of Limpopo in Polokwane on Friday.

Lumumba is the director and CEO of the Kenya School of Law and author of books on legal subjects.

Tiro was a student activist who was killed by a parcel bomb while he was in Botswana in 1974. He had been expelled from the University of Limpopo, then known as Turfloop, for making a speech critical of Bantu education.
