Ukrainian President Volodymyr Zelensky has said his Russian counterpart Vladimir Putin will not stay longer at the post since all totalitarian regimes end the same way.

"Of course a new president will appear there. Of course it will happen. What kind of president it will be, I don't know. But we can see that all totalitarian regimes end the same way," he told the Guardian in an interview.

To the journalists' remark that Putin would never simply give up power to a Zelensky figure in Russia, the Ukrainian president said: "I don't want people to die anywhere. But we should understand that if you keep tightening the spring, at some point it will snap."

Zelensky thinks the era of the political outsider is just starting and his own campaign model could succeed elsewhere. "I am certain it could, especially where people are tired, where they are running like squirrels on a wheel, and there are these long-standing politicians with big financial resources. In these places, where people are searching for a breath of fresh air, it should work."
