using data on the content of debate associated with votes in the uK House of Commons from 1992-2015, this article examines how government party MPs employ language in legislative speech when they vote against the party line. We find a robust statistical association between dissent on votes and the use of firstperson pronouns, simpler language, and giving longer speeches. using a random forest algorithm for classification, we find that these language covariates are predictive of rebellion. the use of simpler, first-person language has implications for political representation and offers new insight into how MPs use votes to distinguish themselves from their party, perhaps reflecting attempts to connect with constituents.
