On March 1, Steven Moffat was a guest of Trinity College, Dublin and took part in an interview and Q & A session - listen to it in the player below. During the Q&A the current showrunner addressed the topic of why so few female writers are involved with Doctor Who (the last being Helen Raynor for the 2008 Sontaran two~parter), here's what he said:
"I don't know why. We chase both sexes. There are many [female writers]. I think a female voice would be fantastic. But we're getting no luck there." Joking he added, "I have a folder of women. They all said no!"
