This paper extends our models of public preferences for the representational relationship, assessing the extent to which members of the public think that bargaining and compromise versus standing on principles should influence MPs decision taking in Parliament. To do so, we make use of experiments embedded into the 2011 Scottish Election Study asking people to rate how important bargaining is in political decision taking in ''average'' groups of people versus groups of MPs in parliament. Initial findings show that members f the public clearly hold MPs to different standards, preferring that they stand more on ''principle'' rather than engaging in bargaining and compromise (which is preferred for groups of people).
