Sharon FranklinPlayed by Nicola Walker

Assistant Commissioner Franklin fields some of the force’s trickiest situations with unimpeachable skill and a trademark penetrating glare, but plays it somewhat low-key when it comes to interdepartmental politics, less than entirely comfortable in the spotlight. She nevertheless makes a big impression on new communications chief Liz Garvey, in contrast to Commissioner Miller’s de facto right-hand-man, Sharon’s fellow assistant commissioner Charles Inglis.
