I suggest we make a replacement with the Russian Federation, their boyfriend for our boys and girls who are in Russian captivity. This is the proposal of the Ukrainian president Volodymyr Zelenski, which he gave late last night in his address to the public.

He wants to replace a captured pro-Russian politician and close ally of Russian President Vladimir Putin. Victor Medvedchuk.

Ukraine's security service says it has arrested the fugitive Medvedchuk, who was under house arrest on suspicion of treason but tried to flee a few days after the Russian invasion.

The media writes that Medvedchuk is considered the closest and most influential ally of Putin in Ukraine.

Ukrainian authorities suspect Medvedchuk of high treason and attempted robbery of Crimea's national resources, which Moscow annexed in 2014.
