THE portrayal of the police and crime commissioner in the hit TV show Line of Duty has been slammed as “totally unrealistic” by a man who’s been doing the job for real for five years.

North Wales Police and Crime Commissioner Arfon Jones is a big fan of BBC One’s ratings blockbuster but says that the behaviour of his television counterpart, Rohan Sindwhani, doesn’t ring true.

The fictional commissioner who lords it over Central Police plays a key role in the mind-bogglingly complicated twists and turns of the plot in Line of Duty.

Sindwhani was elected on the platform of "shaking things up" and exposing police corruption in full.

But he’s then forced to lie about the outcome of the Operation Pear Tree investigation into institutionalised links with organised crime when his senior legal counsel, Gill Biggeloe, was an active member of the Organised Crime Syndicate that killed police officers.

Theories and predictions are swirling around Line of Duty as the sixth series prepares to come to an explosive end on Sunday night.

The seventh climactic episode will be one of the most eagerly-awaited TV events of recent years.

While series five revealed that the bent copper “H” was in fact not one person but several, the search remains ongoing for the last “H”, also referred to as “the fourth man”.

There has been some speculation that Sindwhani may be unmasked as the last “H”.

Mr Jones has confessed to being an avid watcher of the series and has thoroughly enjoyed most of it.

He knows policing inside out, having served and an officer of North Wales Police before retiring as an inspector after 30 years on the force.

He was elected to become the region’s second ever PCC when as the Plaid Cymru candidate he won the 2016 election with a landslide majority of 25.000.

His term of office is now drawing to a close because he is standing down at the election on Thursday, May 6.

Interviewed about Line of Duty on Radio 4 , Mr Jones said: “I don’t think it’s particularly realistic, it’s not true to life.

“A police and crime commissioner wouldn’t be getting involved in the operational side of policing as that police and crime commissioner does.

“The most unrealistic part is when the PCC resigns after the Chief Constable calls for less political interference. That just wouldn't happen, a far more likely scenario would be for the PCC to call for the Chief Constable to resign.

“It annoys me. Clearly, whoever has advised the producers of Line of Duty are either not aware of the role of police and crime commissioner or they are trying to blacken the reputation of the role?”

“After initial concerns, I now fully support the concept of PCCs as they are more effective and efficient and conduct better scrutiny than 17 members of a police authority.”

But like the rest of the show’s fans Mr Jones can’t wait to find out who “H” is.

Line Of Duty secured its most-watched episode on Sunday night:

The penultimate episode of the police procedural, created by Jed Mercurio, earned an average of 11 million viewers and 51.7% of the audience share, according to the broadcaster.

The sixth series of the BBC One show, starring Vicky McClure, Adrian Dunbar, Martin Compston and Kelly Macdonald, will come to an end this weekend. A seventh series has not yet been announced.

Line Of Duty returned to screens in March with 9.6 million viewers, up on the last series’ finale, which earned 9.07 million.

Mercurio, whose credits also include Bodyguard and Bodies, said: “Thanks so much to everyone watching #LineofDuty6. The whole production team is thrilled and flattered by the amazing response.”

The new series has seen anti-corruption unit AC-12 take on a new case, but Detective Inspector Kate Fleming (McClure) is no longer on the squad and is working on a murder investigation with a different department, which has come under suspicion from AC-12.

Sunday’s episode saw Acting Detective Superintendent Joanne Davidson (Macdonald), boss of the suspected department, unmasked by AC-12 and secrets about her family background revealed.

The final episode on Sunday will see the search for “H” – the corrupt officer responsible for the mass conspiracy – come to an end.

A trailer released on Monday offered fans a first glimpse of the series finale.

“All these suspicious deaths were orchestrated by one officer in particular – H, the fourth man,” says Superintendent Ted Hastings.

The AC-12 team are seen in a shootout before viewers are told: “Every investigation has led to this.”
