The 25th series of The Bill, a British television drama, was the penultimate series of the programme. This series saw the show transition to a post-watershed time slot of 9pm, dropping from two episodes to one week-by-week as ITV aimed to save up to £65 million. Producers used the post-watershed slot to introduce "darker, more gritty" storylines. DI Samantha Nixon left prior to the transition, after seven years on the show, in a special two-parter storyline that included a cameo appearance by her daughter Abigail , who was a recurring character on the show from 2002 to 2005. A six-part storyline came as part of the end of the twice-weekly episodes, Conviction, that concluded with four cast members leaving, including Superintendent John Heaton DCI Jack Meadows was promoted into the role. The four characters were part of seven who left as part of the revamp, however the axing of PC Tony Stamp after 22 years on the show proved controversial.
