David Walliams’ long-standing relationship with HarperCollins UK has come to an abrupt end. The publisher has confirmed it will no longer release new books by the bestselling children’s author, following an internal investigation into allegations of inappropriate behaviour towards female staff. For an author who once dominated the UK children’s book market, the decision marks a dramatic shift in fortunes.
According to reports, the investigation concluded in 2024 after serious concerns were raised internally. While HarperCollins has not shared specific details publicly, it made clear that employee wellbeing was the driving factor behind the final decision.
Staff Concerns Sparked the Investigation
The inquiry reportedly began in 2023, after a junior female employee raised concerns about Walliams’ conduct. As the investigation progressed, multiple staff members were interviewed. Employees were allegedly advised to attend meetings with Walliams in pairs and discouraged from visiting his home, highlighting the level of discomfort within the organisation.
The final call was made by HarperCollins’ new CEO, Kate Elton, who took over leadership in October. The company said the decision followed careful consideration and reflected its commitment to maintaining a safe and respectful workplace.
From Publishing Powerhouse to Sharp Decline
The split brings an end to one of the most profitable author-publisher partnerships in recent UK publishing history. At his commercial peak, Walliams was a juggernaut. In 2018 alone, his books accounted for around 44 percent of HarperCollins UK’s children’s sales, an extraordinary figure for a single author.
Globally, his titles—including Gangsta Granny and other hugely popular releases—have sold more than 60 million copies and been translated into 55 languages. However, that dominance has waned. Industry data suggests Walliams’ book sales fell by more than 60 percent during the summer of 2025, signalling a sharp downturn even before the publishing decision became public.
Reputation Already Under Pressure
This latest development adds to a series of setbacks for Walliams. In 2022, leaked transcripts from Britain’s Got Talent revealed offensive and vulgar remarks made about contestants during filming breaks. The backlash was swift, and he stepped away from the show in 2023.
Those controversies stalled his television career and significantly damaged his public image. Now, losing his publisher represents another major blow to his professional standing.
What Comes Next
At 54, and despite being awarded an OBE in 2017, Walliams faces an uncertain future. His most recent book, Santa & Son, has already been published, but HarperCollins has confirmed no further titles will follow under its imprint. For a figure once considered untouchable in children’s publishing, this moment signals a profound turning point.
