Nick Wallis brings new revelations from Post Office scandal to Cranleigh

Award-winning journalist Nick Wallis returns with The Great Post Office Cover-Up, an investigative live show exploring the Horizon scandal, the fight for justice and the revelations still emerging.

Countless lives were torn apart by the Post Office Horizon scandal which led to hundreds of innocent people fighting to clear their names.

Following a sold-out tour and widespread acclaim for his reporting on the Post Office Horizon scandal, award-winning journalist, broadcaster and author Nick Wallis returns with a compelling new live show, The Great Post Office Cover-Up, on Wednesday 11 November 2026.

Drawing on more than 15 years of investigative journalism and inspired by his forthcoming second book, Wallis takes audiences beyond the scandal itself to expose the extraordinary efforts made to conceal one of the greatest miscarriages of justice in British history.

Through meticulous research, first-hand testimony and powerful storytelling, The Great Post Office Cover-Up examines how hundreds of innocent Subpostmasters were wrongly accused, prosecuted and, in some cases, imprisoned because of faults in the Horizon computer system. More significantly, it shines a light on the years of institutional denial, obstruction and cover-ups that followed.

As the public inquiry continues to uncover new evidence, Wallis guides audiences through the latest revelations, explaining their significance and the ongoing struggle for accountability. Combining forensic analysis with deeply human stories, the show explores the devastating personal consequences for those affected and the remarkable determination of campaigners who fought to expose the truth.

Described by Private Eye editor Ian Hislop as “an extraordinary journalistic expose of a huge miscarriage of justice”, Wallis has become one of the foremost authorities on the scandal through his work for BBC Panorama, BBC Radio 4, Private Eye and his bestselling book The Great Post Office Scandal.

Part live investigation, part courtroom revelations and part personal testimony, The Great Post Office Cover-Up is a gripping, revealing and often moving account of a national scandal that continues to unfold. For audiences who thought they knew the story, Wallis reveals there is much more still to come.

The performance will be followed by a live audience Q&A, with opportunities to discuss the latest developments in this extraordinary case.

The Great Post Office Cover-Up is essential viewing for anyone interested in justice, accountability and one of the most important public scandals of modern times.
