Romania is the "champion of governmental instability" in a sample of 16 European states, shows the report "Governmental Stability in Europe (2007 - 2025). A brief analysis of the duration of prime ministerial mandates in 16 European states", published on Monday by the Center for the Promotion of Participation and Democracy (CPD) within the National School of Political and Administrative Studies (SNSPA).According to the analysis, Romania stands out as the state with the highest "governmental volatility", having 13 prime ministers in the analyzed period and the shortest average duration of the mandate, of 19.1 months.At the opposite end, Hungary, Spain and Germany record a high level of stability, each having only three prime ministers in the analyzed interval and average durations of mandates of over six years. The data show a clear negative correlation between the frequency of changes in prime ministers and the longevity of their mandates: the more frequent the changes, the shorter the duration of the mandates.This instability indicates structural difficulties in ensuring decision-making coherence and the continuity of public policies.Romania has the shortest average duration of a prime minister's mandate, namely 17.5 months. In other words, between January 1, 2007 and December 3, 2025, a prime minister served, on average, 17.5 months, that is, less than a year and a half.The approach aimed to create a comparative picture of prime ministers and the duration of their mandates, using a simple descriptive indicator, intended to provide the public with a clear benchmark and to create a factual basis that can support the development of more in-depth analyses. The study analyzes government stability in 16 European countries (Belgium, Bulgaria, Czech Republic, Croatia, France, Germany, Greece, Italy, Poland, United Kingdom, Romania, Slovakia, Slovenia, Spain, Sweden, Hungary), by evaluating the duration of prime ministerial mandates, between January 1, 2007 and December 3, 2025. Both the frequency of changes at the top of the executive and the effective duration of the time spent in office by each prime minister are examined.The comparative analysis highlights significant differences between European countries in terms of the frequency of changes at the top of the government and the effective duration of mandates.
