Famous Ugandan writer, academic and political activist Dr Stella Nyanzi has castigated leaders of opposition political party and pressure groups, including Robert Kyagulanyi aka Bobi Wine of the National Unity Platform (NUP) for reportedly not being committed to the struggle to end President Yoweri Kaguta Tibuhaburwa Museveni’s rule, and for shunning efforts by Dr Kizza Besigye.
