Rowling fumes against 'Potter' spoilers

JK Rowling has criticised US newspapers that have revealed plot details from the final Harry Potter novel.

Reviews of The Deathly Hallows have been featured in several US publications – including The New York Times - in breach of the publisher's embargo.

However, a spokesperson for Bloomsbury Publishing insisted that the reviews are based on false copies of the book, saying: "The release date and time embargo of 00.01 on July 21 is being enforced unflinchingly and without exception by the publishers."

Rowling added: "I am staggered that some American newspapers have decided to publish purported spoilers in the form of reviews in complete disregard of the wishes of literally millions of readers.

"I am incredibly grateful to all those newspapers, booksellers and others who have chosen not to attempt to spoil Harry's last adventure for fans."
