The 79-year-old Nazarbayev announced his resignation in March 2019 after ruling the oil-rich former Soviet republic for almost 30 years. But he continues to lead the ruling Nur-Otan party and the country's powerful Security Council.

He also enjoys the broad benefits of the title of "elbasy" – the leader of the nation.

Nazarbayev's opponents say he de facto continues to run the country of 18 million by supervising the actions of incumbent President Qasym-Zhomart Toqaev.
