Talking to the press about her big win in the winners' room, Kate said: "I'm shocked. I'm completely shocked.
"I honestly did not think we were going to win so I'm genuinely shocked but so proud because we made something that really touched people and that people really thought about and talked about and are still talking about and still come up to me in the street and talk to me about. That is the most powerful thing about the job that we do is that sometimes you can really reach people."
