The reports, published overnight after a court fight, detail accusations dating back to 2003, when Walliams was in his 30s. The Guardian said multiple women alleged he abused his power and celebrity status to prey on them for sexual purposes when they were teenagers or young women. One woman alleged he sexually assaulted her at his London home when she was 15; others accused him of grooming them as teenagers. Walliams, 55, denied abusing his position of power in a letter to the investigating journalists, saying he was "not a sexual predator" and had not broken the law. He said he regretted not always taking others' feelings into account.

London's High Court rejected his injunction application on November 3. Walliams had argued publication would put him at risk of suicide; the judge acknowledged his psychiatric vulnerability but said the evidence did not establish that suicide was inevitable. A deadline for appeal passed overnight, allowing the outlets to publish. No police charges have been laid and there is no suggestion he is under police investigation. The Metropolitan Police said it had contacted the outlets to ensure potential victims knew how to report criminal allegations.

HarperCollins UK dropped Walliams in December 2025 after the Daily Telegraph reported the publisher had investigated harassment allegations involving junior female employees. The BBC said it was removing some programs, including Little Britain, while reviewing material featuring or written by him. His literary agents said they were no longer representing him, and producers of the film Fing! said his cameo had been removed.
