Vladimir Putin stars in judo DVD

Russian Prime Minister Vladimir Putin has released an educational judo DVD.

Putin, a martial arts black belt, is seen in a judo robe throwing his practice partner to the floor.

Addressing the camera, he said: "In a bout, concessions are permissible but only in one case - if it is for victory."

Putin's former instructor Anatoli Rakhlin credited the politician with the rise in popularity of martial arts in Russia, saying: "It's important that our Prime Minister is a sportsman and not a drunk.

"Victory is an integral part of judo. It goes back to when a Japanese master looked at a cherry tree laden with snow. The branches bent - but then flung the snow off. It's about giving and then winning."
