Transparency International releases their 2010 corruption index of most corrupt countries in the world.
Transparency International has released their 2010 corruption perception index. The most corrupt country in the world is Somalia, followed by Myanmar, Afghanistan and Iraq. That doesn't exactly reflect well on U.S. efforts. Incidentally, the U.S. is tied for 22nd with Belgium. And the least corrupt country: it's a three-way tie between Denmark, New Zealand and Singapore.
