Political party leaders have to attend different scenarios. At the same time that their audience is changing, they have to change their speeches. Also, their speeches are not only based on the traditional left-right scale position to explain every single issue. Issues like decentralization or devolution have developed the political discussion beyond that. In addition, in multilevel countries, party leaders have to deal with different territorial audiences. In an audience like parliaments, the influence of MP’s from high regional identity territories and how political leaders manage this presence are essential for their speeches. Are parliamentary speeches significantly decentralized than Party Conferences speeches with respect to speeches position over decentralization? The primary assumption is that political party leader’s change their speeches over decentralization depends on their audience. To predict party leaders’ position over decentralization, I use data from supervised speeches analysis from the United Kingdom and Spain. I analyze parliamentary investiture speeches and national party conferences speeches as different audiences. I expect that party leaders have a stronger position over decentralization when they have to take a position in front of MP’s from different regions than when they have to present intra-party speeches. These results hold relevant implications in terms of study political leaders in multilevel institutions and multilevel countries. Also, the use of quantitative text analysis method is an essential contribution to the speeches analysis field.
