Are holders of important ministerial positions more likely to survive in cabinet than their colleagues who hold less important positions? This study examines the relationship between the importance of a ministerial position and the length of time ministers are able to survive in government. It is based on an original dataset of cabinet ministers in seven West European countries from 1945 to 2011. Employing a little-used measure of ministerial survival based on overall time in government, it is found that holders of important ministerial positions are more durable than their colleagues who hold less important ministerial positions. Age, prior government experience and the size of the party to which the minister belongs are also associated with consistently significant effects. Further, the study explores the determinants of survival for two types of risk – exiting government with one’s party and exiting without it – showing that the effects of ministerial importance and other covariates are markedly different for these two types of exit. The findings have important implications for the understanding of ministerial and governmental stability.
