Doctor Who chief writer Steven Moffat has attacked fans of the show who reveal crucial plot lines ahead of transmission.
"You can imagine how much I hate them," he told BBC Radio 5 live. "It's only fans who do this, or they call themselves fans.
"I wish they could go and be fans of something else."
Before the current series began, a fan posted the entire plot of the first two episodes on an internet forum.
