Putin calls former world champion to war in boxing

Giant Nikolai Valuev, who is 2.13m long, is the world's longest and worst champion in boxing history.

At its height, it weighed 149kg.

After retirement in 2009, he went to politics and joined the Russian parliament, or Duma, in 2011 as a member of the United Russia party that supports Putin.

Because of his enormous size, a special chair had to be made for him to sit down when he was in parliament.
