Corruption continues to be one of the biggest challenges facing Europe. Whilst the nature and scope of corruption varies from one EU State to another, it harms the EU as a whole in terms of reducing levels of investment, obstructing the fair operation of the Internal Market and having a negative impact on public finances. The economic costs incurred by corruption in the EU are estimated to amount to around EUR 120 billion per year. Corruption can also undermine trust in democratic institutions and weaken the accountability of political leadership. Moreover, it enables organized crime groups use corruption to commit other serious crimes, such as trafficking in drugs and human beings.
