Lee Kuan Yew
Born
Lee made clean government central to Singapore's governing identity. The 1960 Prevention of Corruption Act strengthened enforcement powers, giving the pledge a legal mechanism rather than leaving it at ministerial example. The Corrupt Practices Investigation Bureau predated his government, however: it was established in 1952. His place in this history rests on strengthening and politically backing an existing institution, not personally inventing anti-corruption enforcement.

Murray MacLehose, Baron MacLehose of Beoch
Born
MacLehose became associated with Hong Kong's break from police-led corruption investigations when his government established the ICAC in 1974, following an inquiry and public pressure. Giving a separate body the job changed who could investigate whom. The story also includes compromise: his 1977 partial amnesty curtailed investigations into many earlier offences. Institutional independence and the limits imposed on retrospective accountability belong in the same account.

Thomas Sankara
Born
Sankara's public declarations of modest personal assets helped make him an enduring symbol of resistance to elite enrichment in Burkina Faso. The appeal was unusually personal: a leader visibly rejecting the privileges associated with office. That reputation cannot stand in for an assessment of his government's treatment of opponents. Amnesty International documented prisoners of conscience and detention without trial under his rule, a serious limit to any uncomplicated story of accountable government.

Jerry Rawlings
Born
Rawlings built a powerful anti-corruption identity around denunciations of Ghana's ruling elite and the 1979 military takeover. The campaign's punitive spectacle matters as much as its language of public probity. Eight senior officers, including three former heads of state, were executed that June; Amnesty International found that they had not received public or fair trials. He illustrates how cleansing rhetoric can mobilise support while bypassing the safeguards that make accountability credible.

Julius Nyerere
Born
Nyerere's association with public integrity had a concrete expression in the leadership code accompanying Tanzania's 1967 Arusha Declaration. Restrictions on business interests and property income aimed to separate office from private accumulation. They made personal conduct part of the governing project's public identity. The code was substantially relaxed in 1991, after his presidency, showing that an austere political example and a durable system for regulating conflicts of interest are different achievements.

V. P. Singh
Born
Singh turned the Bofors arms-contract controversy into a defining issue of his campaign against Rajiv Gandhi's government before the 1989 election. As prime minister, he told Parliament that Bofors would be barred from future contracts while the existing agreement was reviewed. This entry concerns the political force of demands for disclosure and investigation. A successful campaign against alleged wrongdoing is not itself a judicial finding against the people it targets.

Alexei Navalny
Born
Navalny made allegations about elite wealth and corruption central to Russian opposition politics, with anti-corruption protests turning investigative claims into collective action. His own prosecutions also require scrutiny rather than automatic acceptance as proof of wrongdoing. In the Kirovles case, the European Court of Human Rights found that Navalny and his co-defendant had not received a fair trial because criminal law had been applied arbitrarily. That specific ruling is distinct from treating every campaign allegation as established fact.

Boris Nemtsov
Born
Nemtsov used reports to challenge the public account of spending under Vladimir Putin. His 2013 report on the Sochi Olympics, co-authored with Leonid Martynyuk, made alleged inflated costs and corrupt enrichment a political issue before the Games. The large sums attributed to corruption were the authors' estimates, not an independently audited total or a court award. His significance here is the use of an organised, contestable documentary case to challenge official prestige spending.

Corazon Aquino
Born
Aquino's break with Ferdinand Marcos's rule gave the recovery of alleged ill-gotten wealth a prominent place in the Philippines' democratic transition. Her first executive order in February 1986 created the Presidential Commission on Good Government to pursue that task. The important institutional move was to turn a movement's demand into investigative and recovery machinery. Creating the commission did not prove every claim or complete the long litigation required to establish ownership and recover assets.

Benigno Aquino III
Born
Aquino made the connection between honest government and reduced poverty the organising promise of his 2010 presidency. His inaugural address explicitly carried the campaign's anti-corruption message into government. The constitutional test came from his own administration's spending: in 2014 the Supreme Court held certain acts under the Disbursement Acceleration Program unconstitutional. That ruling was not a criminal conviction of Aquino, but it prevents a clean-government slogan from substituting for scrutiny of executive methods.

Fernando Collor de Mello
Born
Collor campaigned in 1989 against privileged public officials and became Brazil's best-known example of the distance between a cleansing image and later accountability. His 1992 resignation and Senate disqualification must be distinguished from his 1994 criminal acquittal for insufficient evidence in the PC Farias case. A separate case produced his 2023 conviction for passive corruption and money laundering. Combining these proceedings into one verdict would obscure exactly what was, and was not, legally established.

Sergio Moro
Born
Moro became a public face of Brazil's Lava Jato investigations before moving from the judiciary into government and elected politics. His celebrity as an anti-corruption judge makes the safeguards around judging especially important. In its 2022 findings on Lula da Silva's case, the UN Human Rights Committee identified violations including the right to an impartial tribunal. This concerns the fairness of particular proceedings; it neither validates every accusation nor erases every corruption case investigated under Lava Jato.

Mikheil Saakashvili
Born
Saakashvili's anti-corruption image preceded Georgia's 2003 Rose Revolution, including a public confrontation over senior officials' expensive homes. In office, his administration substantially reduced everyday bribery and changed services such as policing and public administration. Transparency International nevertheless identified weak parliamentary and judicial checks and politically dependent oversight bodies. The useful distinction is between making routine services cleaner and ensuring that those at the top can themselves be independently investigated.

Ellen Johnson Sirleaf
Born
Johnson Sirleaf presented corruption as a central enemy of Liberia's post-war recovery and signed the law creating its Anti-Corruption Commission in 2008. That provided an institutional expression of a highly visible promise. By her final annual address in 2017, she acknowledged that the pledge had not been fully met. Persistent scandals and criticism of family appointments complicated the reforming image; those criticisms should be identified as such, not converted into an unsupported personal criminal conviction.

John Magufuli
Born
Magufuli's early presidency in Tanzania attracted attention for abrupt action against waste and suspected wrongdoing, including dismissals in port and revenue administration. These visible interventions helped create the image of a leader willing to confront official privilege. Human Rights Watch subsequently documented restrictions on independent media, civil society and criticism. Removing officials and constraining independent scrutiny are separate actions, even when a government presents both within a programme of discipline and reform.

Mwai Kibaki
Born
Kibaki entered Kenya's presidency in 2002 promising a decisive break with corruption and appointed John Githongo to a senior ethics and governance role. The Anglo Leasing controversy then exposed the difficulty of investigating deals involving a reforming government's own circle. Githongo resigned and made allegations about obstruction; Kenya's truth commission later examined the scandal while acknowledging unresolved facts. Kibaki belongs here as a symbol of public expectations whose test came from within his administration, not as a shorthand for a proven personal offence.

Beppe Grillo
Born
Grillo's 2007 V-Day campaign turned anger at Italy's political class into demands for changes such as excluding convicted politicians from Parliament and limiting terms. His blog and local organising networks helped carry that message into the movement that became Five Star. The mechanism was political mobilisation through a recognisable outsider, rather than an investigative office. Sweeping claims that an entire political class was corrupt were campaign rhetoric, not findings about every individual politician.

Andrés Manuel López Obrador
Born
López Obrador placed ending corruption at the centre of his promise to transform Mexico, linking it to a public style of austerity and opposition to entrenched privilege. The Segalmex food-agency scandal became a concrete test of that claim. In September 2024 his government acknowledged unresolved funds and criminal complaints, while distinguishing audit queries from established losses. The case shows why a leader's personal message must be assessed alongside procurement controls, investigations and the conduct of institutions under that administration.

Anna Hazare
Born
Hazare's 2011 fasts made the demand for a national anti-corruption ombudsman a mass political issue in India. He was a campaigner outside elected office, and government negotiations with his representatives did not remove Parliament's responsibility to decide the law. The Lokpal and Lokayuktas Act followed in 2013, while the first national chairperson took office only in 2019. That gap between mobilisation, legislation and operation is central to judging what a symbolic campaign actually delivered.

Arvind Kejriwal
Born
Kejriwal's work on citizens' access to information, followed by the anti-corruption movement and the formation of AAP, made public integrity central to his political identity. Later liquor-policy allegations tested that reputation but should not be presented as convictions. In February 2026 a Delhi court discharged him and the other accused in the CBI case; the agency challenged that decision. Those dated developments are distinct from both his earlier campaigning record and any final resolution of the separate legal proceedings.
