The political landscape in the UK has become increasingly unstable, with six prime ministers since 2015, including Rishi Sunak and Keir Starmer. This instability is attributed to a fragmented party system, where Labour and Conservative parties now capture less of the total vote compared to previous decades. Major political shocks, such as Brexit, the COVID-19 pandemic, and international conflicts, have compounded the challenges faced by leaders, leading to public dissatisfaction. Recent data shows a decline in approval ratings for prime ministers, with the public increasingly blaming the government for political failures rather than individual leaders. The first-past-the-post electoral system exacerbates this issue, as seen in the 2024 election, where Labour secured less than 34% of the vote but over 63% of the seats, creating a legitimacy crisis. The cumulative effect of these factors suggests that the trend of high turnover among prime ministers is likely to continue until the political turmoil subsides.
