The BBC is using Doctor Who to "promote" a gay agenda, according to viewers' complaints which have been published in a report by the BBC Trust.
In the report, which records complaints made between February 2013 and September 2014, three viewers said that the science fiction show was "promoting homosexuality".
In a scene from Deep Breath, the debut story of Peter Capaldi as the Doctor, the lizard woman Madame Vastra was seen kissing her human wife, Jenny.
The lesbian couple, played by Neve McIntosh and Catrin Stewart, have been in the show for three years but this was the first time that they had been seen kissing.
The episode was watched by 7 million people.
Since the show's successful return nine years ago, it has featured several gay characters including the "omnisexual" Captain Jack Harkness, played by John Barrowman.
Other complaints received by the BBC included the alleged ridiculing of tall women in Miranda, and an inappropriate use of The Hallelujah Chorus in The Great British Bake Off.
