Independence in Europe: Regionalist Party Rhetoric and the EU in a Post-Brexit United Kingdom

In the wake of Brexit, how has the framing of the EU and independence evolved among regionalist parties in the devolved regions of the UK? The effects of a multilevel structure such as the EU on regionalist parties has been examined, yet European disintegration is novel and thus yet to be fully explored. Has the framing of the EU by these parties shifted, and if so, how? In this article, I analyze 19 regionalist party manifestos between 2011 and 2022 through the lens of rational choice and discursive institutionalism to examine the effects of Brexit on the framing of the EU. At a rhetorical level, these parties have engaged in the subsuming of the EU, rhetorically tying their independence or enhanced autonomy to Brexit. Sinn Féin, Scottish Nationalist Party, and Plaid Cymru have used the critical juncture of Brexit to incorporate the EU into their regionalist rhetoric. By examining the effects of European disintegration on regionalist political parties, we can better understand the role that current events play in the fluidity of party positions as presented in manifestos.
