"Who really is Kazakhstan's leader of the nation?"

Kazakhstan.

"The consensus among Kazakhstan watchers is that the former president is trying to contain his successor."

"In his capacity of Leader of the Nation, a bespoke title created in 2010, Nazarbayev retained the right to continue influencing policymaking in important ways. Nazarbayev is also lifetime chairman of the Security Council, the body that oversees all the nation’s security bodies. --- Dariga Nazarbayeva was appointed chair of the Senate days after her father resigned as president. That position means she would take over if Tokayev were ever to resign or become incapacitated.
Mallinson said that this suggests “the presidency will ultimately return to the Nazarbayev family, in some shape.”
