The European Union adopts a new harmonised criminal law framework to prevent and combat corruption
According to the latest corruption index published by Transparency International, although Europe ranks as the least corrupt region, the reality is that anti-corruption measures in recent years have been limited.
Given this trend, in December 2025 the Parliament and the Council provisionally approved a new directive to tackle corruption in the European Union. This directive emerged against a backdrop of a crisis of confidence following the Catargate scandal in 2023, which highlighted deep-seated vulnerabilities in the integrity mechanisms of European institutions. However, beyond the political enthusiasm, the true impact of this directive will depend on one key factor: its effective implementation by Member States.
This initiative has recently taken a further step forward, with the European Parliament giving the final green light to the new EU anti-corruption legislation, adopting in March this year a new harmonised criminal law framework to prevent and combat corruption in the European Union.
The Directive establishes common definitions of corruption offences, including bribery, embezzlement, obstruction of justice, influence peddling, the unlawful exercise of functions, illicit enrichment linked to corruption, concealment and corruption in the private sector. Furthermore, it harmonises the rules on penalties, introducing minimum and maximum levels designed to ensure a more consistent approach across the Union.
The central aim of the recently adopted legislation is precisely to close the enforcement gaps that have historically characterised European anti-corruption policy, particularly in cross-border cases. Although Member States retain a certain degree of flexibility, the new system seeks to prevent national differences from leading to impunity or unequal responses to similar conduct.
The legislation also significantly strengthens cooperation between key institutions such as the European Anti-Fraud Office (OLAF), the European Public Prosecutor’s Office, Europol and Eurojust, improving information exchange and operational coordination. It also introduces an obligation for Member States to publish comparable and automated data annually, paving the way for greater transparency and evidence-based policies.
Another key element is the strengthening of national structures: Member States must adopt anti-corruption strategies that are regularly updated, based on risk assessments, and involving civil society in their design. Furthermore, they must ensure the existence of independent and adequately resourced bodies to prevent and combat corruption, as well as robust systems regarding conflicts of interest, transparency in political financing and public integrity.
Dutch MEP Raquel García Hermida-van der Walle highlighted the structural dimension of this reform, stating that corruption has not only an economic cost, but also a human and institutional one, eroding democratic trust and directly affecting the functioning of the rule of law.
According to a recent OECD report assessing integrity systems in 62 countries, including several European ones, there remains a significant gap between strict rules in theory and their effective enforcement in practice, particularly regarding conflicts of interest. Added to this is public perception: according to the Eurobarometer survey “Citizens’ attitudes towards corruption in the EU in 2025”, almost seven in ten Europeans consider corruption to be widespread in their country, and two-thirds believe that high-level cases are not adequately prosecuted.
However, beyond the political consensus on the seriousness of the problem, the real challenge remains its effective implementation. European experience shows that the gap between regulation and practice is one of the main obstacles in the fight against corruption. In this regard, the effectiveness of the new directive will depend not only on its legal ambition, but on the actual capacity of Member States to apply it consistently and sustainably.
In parallel with this legislative progress, initiatives are also emerging that help to strengthen its practical application and reduce the existing fragmentation in European integrity systems. Among these, VoiceGuard stands out, coordinated by the FIBGAR team, a project that addresses precisely one of the most critical aspects of the system: the effective and uniform protection of whistleblowers across the European Union. Through a pan-European approach, VoiceGuard works to identify gaps in protection mechanisms, compile best practices, and develop support and training tools to facilitate the effective implementation of European legislation.
In this regard, the new directive not only strengthens the criminal law framework but also opens up an opportunity to integrate such initiatives into the European integrity architecture, linking the regulatory dimension with the operational one.
In theory, this represents a significant step forward. For years, regulatory fragmentation has been one of the main obstacles in the fight against corruption in Europe. The fact that the same offence can be treated differently depending on the country has weakened its deterrent effect and complicated judicial cooperation. With this new framework, the EU is taking a step towards greater legal consistency.
Finally, one cannot ignore the political divisions within the European Parliament that have led to a stalemate in other complementary processes, such as the creation of an independent ethics body at EU level or the expansion of the powers of the European Public Prosecutor’s Office, which has been postponed until 2027. All of this suggests that, although the legal framework is advancing, political will and operational capacity will remain decisive factors.
In conclusion, the new directive represents a decisive step in the European Union’s anti-corruption architecture. However, its success will depend on more than just its regulatory design: it will require effective implementation, institutional cooperation and tools to bridge the gap between the law and reality. In this endeavour, initiatives such as VoiceGuard can play a significant role by contributing to the practical harmonisation of whistleblower protection and the strengthening of the European integrity ecosystem.
