Multinational pressure group Transparency International has published a study claiming that two-thirds of the world’s biggest defense companies “do not provide enough public evidence about how they fight corruption.” The group says that its Defense Companies Anti-Corruption Index studied the 129 biggest defense companies worldwide with a combined revenue of over $500 billion. Transparency International estimates the global cost of corruption in the defense sector to be at least $20 billion per year, based on data from the World Bank and SIPRI.
