The United Nations is one of the biggest bodies of corruption in the world.
It has admitted to as much recently that there is a need to tackle pervasive organized corruption within its networks. Which often include politicians, civil servants, private sector nongovernmental organizations (NGO's), and members of crime syndicates that work within its ranks.
It has also pointed to the terrible consequences of such complex, multi-jurisdictional corruption but nothing ever happens to correct these issues.
