German TV documentary about doping in athletics

At the start of December 2014, a German TV documentary was aired which alleged that athletics in Russia was rotten to the core with doping being sanctioned and covered up at the highest levels. The implications reach all the way to the IAAF, the world governing body for athletics. It's fair to say that this is probably one of the most significant stories to hit athletics in recent times and will probably have huge repercussions.
