How do party leaders manage diverse preferences over decentralization among party members’ positions? In countries with multilevel institutions, intra-party groups with different regional identities coexist, and these differences likely hold importance for leaders’ positions. Also, MPs from areas with distinct regional preferences seek to draw the party’s position over decentralization towards their region’s preference. The primary assumption is that national party leaders require support from the MP’s elected from high regional identity territories. Therefore, I predict that leaders adapt their speeches to account for position over decentralization depending on the presence of MPs from these regions to maintain their support. To predict the national party leader position on a territorial scale, I will use data from investiture speeches’ in Spain and the United Kingdom. I predict these positions using automated text analysis method Wordscores. I expect to find that the number of MP’s representing high regional identity territories influences the national party leader position over the issue of decentralization. These results hold new implications due to the inclusion of decentralization in the intra-party discussion. Moreover, I contribute to the study of speeches and quantitative text analysis using manifestos mentions over decentralization to establish the scale limits.
