Who are the leaders defending Ukraine's capital?

As Kyiv braces for attacks by Russia, who are the leaders tasked with defending the city? One is a former comedian, the other an ex-boxing champ.

When Volodymyr Zelensky first appeared on TV screens as Ukraine's president, he did so as an actor in a popular comedy series.

But then life imitated art in April 2019 and he became president for real, winning by a landslide with over 73% of the vote.

Now he leads a country of 44 million people, and says he is currently "the number one target" of Russia's forces.

Zelensky has vowed to remain in Kiev.

Like Ukraine’s president, Vitali Klitschko was a political novice before he was elected mayor of Ukraine’s capital in 2014.

The son of a military man stationed at Chernobyl following the nuclear disaster, Klitschko rose to fame as a world heavyweight boxing champ alongside his younger brother Wladimir.

Now the siblings say they will take up arms to fight alongside their countrymen.

"I don't have another choice, I have to do that. I'll be fighting," the mayor told ITV’s Good Morning Britain on Friday.
