Looking at mediated, political and wider public discourses on immigration in Poland since 2015 and exploring these in the context of the country's right-wing populist politics, the paper develops a multi-step normalisation model which allows analysing how radical or often blatantly racist discourse can not only be strategically introduced into the public domain but also evolve into an acceptable and legitimate perspective in perceptions of immigrants and refugees. The paper highlights the strategic as well as opportunistic introduction of anti-immigration rhetoric in/by the political mainstream in Poland in recent years, often on the back of the so-called post-2014 European "Refugee Crisis". It explores normalisation as part and parcel of a wider multistep process of strategically orchestrated discursive shifts wherein discourses characterised by extreme positions have been enacted, gradated/perpetuated and eventually normalised as an integral part of pronounced right-wing populist agenda. The paperfurthers a view that normalisation entails the creation and sustainment of a peculiar borderline discourse wherein unmitigated radical statements are often married with seemingly civil and apparently politically correct language and argumentation. The latter are used to pre-/legitimise uncivil or even outright radical positions and ideologies by rationalising them and making them into acceptable elements of public discourse.
