The Bill: Office Politics

The Sun Hill police had better watch their backs following the arrival of enthusiastic new PC Andrea Dunbar, as unknown to them she's really an undercover reporter out to investigate whether the Met has become too soft on criminals - and she has Supt Okaro bang in her sights. Jack Meadows and Neil Manson clash over the latter's insistence on getting rid of Eva, while Polly returns as the new CAD operator, but feels alienated from her colleagues - a feeling made even worse when she returns home to a shocking message left by a graffiti artist. Doctors actress Natalie Robb joins the cast, alongside Simon Rouse, Andrew Lancel, Diane Parish and Lisa Geoghan
