Series 23 of Casualty begins this weekend with an explosive two-part special airing across Saturday and Sunday nights.

The episodes, entitled 'The Farmead Menace: Parts I and II', see paramedics Dixie (Jane Hazelgrove) and Jeff (Matt Bardock) in an accident which threatens the life of a pedestrian and their jobs, while Tess (Suzanne Packer) is left fighting for her life after becoming impaled on a metal rod.

Here, DS presents a gallery of behind-the-scenes pictures from the first two episodes of the series.

The new series kicks off with the two-parter airing on Saturday, September 13 at 8.20pm and Sunday, September 14 at 8pm.
