A survey carried out by the Transparency International UK has revealed nearly 70% of the 82 countries surveyed had poor anti-corruption controls in their defence sector, and only 2 countries (Germany and Australia) had strong controls. This was based on factors such as Parliament's power over defence policies and the risk of abuse of defence budgets.
The survey also revealed that out of the countries with poor controls, two-thirds were the largest arms importers, and half were the largest arms exporters.
Corruption within the defence sector poses a huge safety threat but also costs the industry an estimated $20 billion a year.
