Exploring unique survey and interview data on the personality characteristics of British politicians, this book provides a timely psychological analysis of those individuals who pursue political careers and how they represent their constituents once elected. Focusing specifically on the Basic Human Values of more than 150 MPs as well as hundreds of local councillors, Weinberg offers original insights into three compelling questions: Who enters politics and how are they different to the general public? Do politicians' personality characteristics matter for their legislative behaviour? Do voters really get the 'wrong' politicians? Taking a fresh psychological approach to issues that are predominant in political science, this book casts new light on the human side of representative democracy.
