a new initiative called EU Leaks: EUleaks is a European platform where you can submit information in a highly secure and anonymous way. Transparency and accountability are essential for democratic governance. The EUleaks project provides a platform for increasing transparency by providing a new tool for information in the public interest to be made available. EUleaks offers a venue for the realisation of freedom of expression as a fundamental right.
