HarperCollins will not be publishing Amanda Knox's memoir Waiting to be Heard in the UK this spring as planned following legal advice.
The publisher had been due to release the title on 9th May.
A spokesperson for HarperCollins said: "Due to our legal system, and relying upon advice from our counsel, HarperCollins UK will not publish a British edition of Waiting to Be Heard, by Amanda Knox, at this time."
HC US has said it will go ahead with publication, scheduled for 30th April.
Knox was convicted of the murder of her roommate Meredith Kercher in Perugia in 2009 following a controversial trial that made headlines around the world. However, in October 2011, Knox was released when the conviction was overturned following a lengthy appeals process. Last month, Italy's highest criminal court overturned the acquittal and ordered a retrial.
Knox's book deal with HarperCollins was announced in February 2012, with Knox being reportedly paid $4m for the title in a seven-way auction. It is described on Amazon as an "unflinching, deeply personal account".
