Harriet Clugston, Investigations Editor

Harriet previously worked for National World, one of the UK’s largest regional and local newspaper publishers, where she initially led the regional investigations team, before moving to its flagship national website NationalWorld.com as data and investigations editor.

She was previously shortlisted for the Private Eye Paul Foot Award for investigative journalism with her regional team, for a project exposing the many ways in which the criminal justice system – and politicians – had failed to live up to the promises of the Modern Slavery Act. She has also previously exposed the disparities in outcomes faced by minority ethnic victims of sexual and domestic violence; documented the UK police forces probing women they suspect of having illegal abortions; and uncovered how official government, police and Crown Prosecution Service figures are giving an inflated picture of how many serious sexual assault suspects are charged, prosecuted and convicted. Her work has been cited in evidence submitted to Parliament, and discussed by politicians in Westminster debates.

Harriet is a two-time Royal Statistical Society Statistical Excellence in Journalism winner and a Regional Press Awards winner, and has been shortlisted for a British Journalism Award, Society of Editors Media Freedom Awards, and the Write to End Violence Against Women and Girls Awards.

Before moving to National World she was a senior reporter at Radar AI, PA’s local data news agency, and before that a local reporter for the Hertfordshire Mercury.

Aaron Walawalkar, Investigative Journalist

Aaron was previously the news editor at independent media outlet EachOther, helping shape its coverage of UK human rights issues ranging from systemic racism to school exclusions. He was also a freelance reporter for the Guardian and the Observer, covering national news and producing exclusive stories on homelessness and disability rights.

In 2019, he won a Google News Initiative-sponsored award for his work at the Ilford Recorder in east London leading a year-long newspaper campaign focussing on rough sleeping. In coordination with the Bureau Local’s Dying Homeless project, he revealed that at least 10 people had died homeless in the borough of Redbridge in the year to October 2018. Six were undocumented Indian migrants stuck in a bureaucratic limbo.

Aaron has a keen interest in migration, homelessness and policing.

Mark Wilding, Investigative Journalist

Mark joined Liberty Investigates in January 2023 after more than a decade as a freelance investigative reporter, covering issues including criminal justice, drugs policy, migrants’ rights, and homelessness.

For eight years he worked as a freelance correspondent for VICE, producing news exclusives, long-form investigations, and television documentaries. This work included a long-running series about councils using anti-social behaviour legislation to target rough sleepers, which helped secure a government intervention to prevent the practice, and an investigation into the origins of synthetic cannabis that was shortlisted for a Criminal Justice Alliance award for outstanding journalism. His coverage of the UK government’s failure to assist child refugees was prominently cited in an inquiry report produced by the Human Trafficking Foundation.

Mark’s other work has included news exclusives for the Guardian and the Daily Mirror. He has investigated the UK’s flat earth movement for Esquire, marathon cheats for the Observer Magazine, and performance-enhancing drugs for Men’s Health.
