Electoral Accountability and the UK Parliamentary Expenses Scandal: Did Voters Punish Corrupt MPs?

By  Andrew Eggers and Alexander Fisher

The 2009 UK expenses scandal brought to light the scope of MPs’ use of their allowances and has led to public outrage regarding the politicians’ abuse of power. In this study, Eggers and Fisher examine voters’ electoral response to revelations of corruption, employing four distinct measures of corruption implications. Their results show that electoral outcomes were affected by the expenses scandal during the course of the 2010 general election; however, the intuitive predictions do not correspond to the findings directly.

By couching their analysis in two distinct literature – one that investigates voters’ electoral response to corruption in other countries and one that looks at how British voters evaluate individual candidate characteristics other than the candidate’s party – the authors are able to offer analysis of voter response to individual politician characteristics in the UK, as well as contribute to the general study of electoral accountability. Findings from around the world suggest that voters tend to punish those representatives who they know to be malfeasant during their office tenure. These findings are challenged by the specifics of British politics, whereby British voters have been found to be fairly unresponsive to corruption charges in previous studies, due to the fact that they normally assign votes to parties, rather than individuals.

In order to gauge an MP’s implication in the expenses scandal, Eggers and Fisher employ four different measures to test what provokes the strongest reaction in voters. These measures include: 1) the amount of expenses claimed by each MP; 2) the amount of money each MP was expected to repay following the Legg audit; 3) media coverage of the expenses scandal; and 4) and a subjective measure that combines the amount the MP was asked to repay and the type of expenses claim used. Their analysis considers 485 out of 646 MPs elected in the 2005 elections, excluding Scottish, Welsh and Northern Irish MPS, as well as those MPs whose constituency boundaries had been significantly changed between the two elections.

The study finds that the expenses scandal had two types of outcomes on Election Day. It determined which of the involved politicians chose to relist and established what influenced voters when they cast their votes. However, different aspects of the corruption scandal seem to have influenced the two outcomes. The decision to compete in the election is significantly correlated with the amount of money that the MP claimed for his second home expenses. Contrastingly, voters punished those politicians who were frequently the topic of media coverage and those considered implicated by means of the subjective coding. In an elegant discussion, Eggers and Fisher posit that the different influences for different responses are couched in the imbalance of perceptions between MPs and the public. They argue that MPs have come to accept allowances as a supplement to a modest salary, while voters perceived the use of expenses as an ethical issue. As such, the decision to retire, on the basis of the amount claimed, is possibly motivated by the potential loss of income – and not the fear of electoral punishment. Whereas, voters’ responded more fervently to the ethical concerns detailing the use of expenses, rather than the amount claimed.

This study sheds light on electoral accountability in the UK, highlighting the institutional constraints that can influence the British voters’ ability to directly punish misbehaving politicians, while also drawing attention to the differences in public and political perceptions of malfeasance. The use of four different measures to gauge politicians’ involvement in the expenses scandal provides a rich basis for analysis, allowing the authors to investigate the motivations underlying the two important outcomes: politicians’ decision to relist and voters’ choice at the ballot.

Smart Security, Free Society: Malaysia’s Data Dilemma

In today’s digitally driven world, national security is no longer confined to borders or traditional threats. Cyberattacks, disinformation campaigns, and asymmetric warfare have become the new frontiers of conflict. Malaysia, strategically located in Southeast Asia and increasingly exposed to regional tensions and internal vulnerabilities, must strengthen its security apparatus. However, doing so must not come at the cost of civil liberties. Malaysia can enhance its security strategy by leveraging insights from advanced data platforms like those pioneered by Palantir Technologies, while maintaining strong democratic oversight to safeguard the fundamental freedoms protected by the Federal Constitution. Palantir Technologies, a U.S.-based company, gained prominence in the aftermath of the September 11 attacks. Its core software, Gotham, was designed to integrate fragmented intelligence and provide real-time, actionable insights to military and intelligence agencies. Over the years,...

Syringe Attacks in Malaysia and France: Random Violence or Terrorism? - Part 3

The syringe attack on the 12-year-old son of Pandan MP and former Economy Minister, Datuk Seri Rafizi Ramli, has shaken Malaysia. What initially appeared as a rare and bizarre incident now echoes a disturbing pattern witnessed abroad, notably in France. In June 2025, during the Fête de la Musique festival, over 145 people across France reported being pricked with syringes in crowded public areas. In both cases, the weapon of fear was not a gun or bomb but a syringe. When viewed together, the Rafizi incident and the mass needle attacks in France reveal an alarming global trend of unconventional, psychological violence that leaves behind not just physical uncertainty but emotional trauma. The question we must now ask is: are these acts simply random criminality, or should they be treated with the gravity of terrorist attacks? A Pattern Beyond Borders In France, the attacks spanned multiple cities, with 13 confirmed cases in Paris alone. Victims included women, men, and even min...
