Following the online leak of the first five scripts of the upcoming season of Doctor Who, the BBC has asked fans not to distribute the documents or spoil the episodes for others.

"We deeply regret this and apologise to all the show's fans, the BBC and the cast and crew who have worked tirelessly making the series," BBC Worldwide said in a statement. "We would like to make a plea to anyone who might have any of this material and spoilers associated with it not to share it with a wider audience so that everyone can enjoy the show as it should be seen when it launches. We know only too well that Doctor Who fans are the best in the world and we thank them for their help with this and their continued loyalty."

The leak includes the script for the season premiere "Deep Breath," and four other episodes the BBC has dubbed as unfinished.

According to Radio Times, the scripts were leaked as they were being sent to the BBC's Latin American headquarters in Miami. “The opening episode is being simulcast globally so of course translations have to be prepared in advance,” a BBC source said.
