Abstract
Research on differentiated integration (DI) has by and large ignored the views of political party actors on DI. Drawing on 35 semi-structured interviews with party actors from seven member states and situated across the political spectrum, we show them to regard DI as divisive and deeply political. We also identify two little explored dimensions affecting their views: namely the wealth of their member state (MS) and its prior experience of DI. Interviewees from richer MS generally favour DI more than those from poorer MS, and those from MS that have not experienced sovereignty or capacity DI welcome DI more than those from MS that have. While the former tend to see DI as allowing both opt outs for MS unwilling or unable to integrate further and enhanced cooperation for MS able and desirous of doing so, the latter fear their MS being excluded and relegated to a second-class status.

Notes
Interviews were planned to be in-person; however, the Covid19 outbreak in March 2020 prompted a shift to online and phone interviews.
Parties were classified as pro-EU or anti-EU based on the latest Chapel Hill expert survey (Bakker et al. 2020).
This view is corroborated by the fact that when we asked respondents what reforms they foresaw for the EU, none of them spontaneously indicated DI as a preferred outcome.
