New series??

Not yet. I think that depends on the ratings of the last series.

I hope they do! ?

It has been axed. Sadly there won't be any more episodes made. A shame, as I thought the last series was the best yet.

ITV has called time on Stephen Tompkinson drama DCI Banks.
The broadcaster said that the fifth series, which aired earlier this year, will be its last.
"After five series, ITV has taken the decision not to recommission DCI Banks. We're grateful to the production team at Left Bank Pictures for creating the world of DCI Banks and the actors Stephen Tompkinson, Andrea Lowe and Caroline Catz for the commitment and dedication they've shown to their roles."
The drama followed the crime-busting fortunes of the central character – a tenacious and frequently grumpy ex-Scotland yard copper Detective Chief Inspector Alan Banks – which was based on Peter Robinson’s novels.
Other characters in the drama included his colleague DI Helen Morton (Caroline Catz) and DS Annie Cabbot, a fellow copper and Banks’ former love interest played by Andrea Lowe.
