SOCHI, Russia (AP) — An interactive website launched Monday by anti-corruption activist Alexei Navalny paints a vivid picture of the suspected cost overruns and conflicts of interest at the Sochi Winter Olympics.

Russia has spent about $51 billion to deliver the Sochi Olympics, which run Feb. 7-23, making them the most expensive games ever, even though as a winter event it hosts many fewer athletes than summer games do.
