WHSmith's ebooks partner Kobo have said they are reviewing its catalogue to remove all graphic titles from its site.
Book retailer WHSmith shut down their website after reports that the book store was selling pornographic ebooks alongside children's titles.
A spokesperson said: "Kobo is working quickly to review its catalogue and remove the content, authors and publishers in question.
"We are also evaluating new procedures to help ensure that this type of content will not become available on Kobo's site, or those of our partners in the future.
"This unfortunate situation is the result of a select group of publishers and authors violating the self-publishing policies of our platform. These titles will be removed and we will address the individuals in question directly."
