Since the January riots, Kazakh President Kassym-Jomart Tokayev has taken several steps to try and weaken the influence of those close to his predecessor Nursultan Nazarbayev, who was dismissed as chairman of the country's security council on 4 February. A day later, Ermek Sagimbayev replaced Karim Massimov at the head of the KNB, the Kazakh internal intelligence service (IO, 17/01/22). For Tokayev, Sagimbayev is an obvious choice given the pressing need to take back control of senior level security.
