confessions of a copper
New series. With the onset of increasingly strict regulations, health-and-safety rules and political correctness, this series looks at whether many professionals have lost the respect and authority they once held dear, as ordinary police officers, GPs and secretaries lift the lid on their working lives. In the first programme, eight police officers describe how they feel life in the force has changed for ever, as they trace the arrival of the panda patrol car, the integration of women, the riots of the late 1970s and early '80s, and seismic shifts in Britain's ethnic and economic make-up.

Michael Portillo uses his 1913 copy of Bradshaw's Continental Railway Guide to explore Poland. He begins in the capital Warsaw, where he takes to the floor to dance to one of Chopin's polonaises, before discovering how the former industrial city of Lodz supplied the vast Russian empire of the early 20th century. He then heads to Poznan and rides one of the few remaining steam-powered commuter trains.
