In the 90’s, the issue of European integration was deeply intertwined with debates of self-determination. In this respect, processes of decentralization and supranational integration have also inspired the Scottish National Party (SNP) who have echoed a federal vision of Europe where they could anchor their nationalist project of self-determination in a context of vertical dispersion of political power (Keating and Hooghe, 1996; Kohler-Koch, 1996; Bomberg and Peterson, 1998; Marks and Hooghe, 2004). However, with the European 2020 Strategy, a new context of functional interdependence between regional, national and European levels of governance has allowed the SNP to contest the limits of British constitutional settlement through “policy delivery” in a polycentric system of governance. With this new vision of Europe, the political strategy has become economically driven and collectively performed in articulation with Scottish stakeholders, in dialogue with the center. Building on a multi-level governance approach (Marks, 1993; Hooghe, 1996; Marks and Hooghe, 2004; Bache and Flinders 2004), this paper shows that since 2007 the SNP have moved from a state-centric to a governance-centric approach to Europe (George 2004; Jessop 2004), which ultimately supports a neo-functionalist vision of Europe (Haas, 1958; Lindberg, 1963).
