Rob Sullivan

Name:	Rob Sullivan (Andrew Knott)
Age:	24
Background:	Ex-Junior Doctor

Rob is the alpha male of the team but Andrew doesn't think that becoming the team leader is necessarily on Rob's agenda: "He's very hands-on, very protective of the rest of the team and because he has this background in medicine; of being a doctor, he's very level headed as well. He will always step up, no matter what is asked, he'll be there and try to make a difference. Rob's a leader in the sense that he wants everything to be right and if it means him being overruled, that's fine, he's wide open to opinion."

Although the main focus of Spooks: Code 9 is maintaining peace in Britain, the team do have time to think about themselves at times and with such a highly charged and intense atmosphere it's no surprise that some team members get particularly close: "There is a bit of a love triangle with Rob, Rachel and Charlie, and for Rob it's really a case of unrequited love," explains Andrew. "Rob's not desperate; he's just very attracted to Rachel. They work together, it happens in offices all over the world! But unfortunately her attention often falls more on Charlie."

If put in Rob's situation himself, Andrew's not so sure he would be able to put himself forward like Rob does in the world of Spooks: Code 9: "I don't feel I'd make a very good spook. You don't know how you'd think or act if something that devastating happened in real life. I don't think I'd be the person to answer the MI5 advert."

Andrew is best known as one of the original History Boys, having starred in both the stage and screen versions of Alan Bennett's hit comedy drama alongside Richard Griffiths, Frances de la Tour and James Corden. He has since appeared in hit TV series Life on Mars, Drop Dead Gorgeous and award winning comedy Gavin and Stacey.
