The article is dedicated to the analysis of the relationship between the EU politicisation and the dynamics of the sanctions regime against the Russian Federation. Based on the logic of the post-functionalist theory of European integration, the issues of European integration and the EU foreign policy within the framework of politicisation at the national level are challenged by Eurosceptic actors, creating impulses, including for the sustainability of the sanctions regime. In this context, understanding politicisation as the polarisation of positions on the EUs anti-Russian sanctions, the increased visibility of this issue in the discourse of institutions/actors and attempts by the latter to expand their influence by promoting initiatives within the framework of the sanctions course, the article analyses the politicisation of anti-Russian sanctions issues by the European Parliament in 2022-2025. The conclusions of the study are that in the case of the European Parliament the effect of limited politicisation within the framework of sanctions policy is formed, which implies the EPs interest in continuing the sanctions course and increasing its place within the framework of the CFSP, but does not lead to the EPs internal polarisation on the issue of anti-Russian sanctions. The latter could serve as a basis for revising/weakening the EPs role as an instigator of new sanctions restrictions against Moscow. Thus, the politicisation of the institution within the framework of the above-mentioned issues works to increase the sustainability of the EU sanctions regime against Russia.
