An MP says he is "shocked and saddened" by "untrue personal attacks" on him by North Wales Police's top two officers.
Richard Brunstrom was the subject of a BBC TV documentary
Wrexham MP Ian Lucas has complained to the police authority about comments by chief constable Richard Brunstrom and his deputy in a BBC TV documentary.
The Labour MP said he no longer had any confidence in Mr Brunstrom and Clive Wolfendale.
The authority confirmed it had received a complaint, but would not comment.
During The Chief, which was shown on BBC One Wales on Tuesday, and will be repeated on BBC 2W on Wednesday, Mr Brunstrom discussed a press release by Mr Lucas which attacked the force for recruiting two web designers.
Talking to Mr Wolfendale, Mr Brunstrom called the MP Ian "Ned Ludd" Lucas.
Ned Ludd gave his name to the Luddites, who protested - often by destroying sewing machines - during the Industrial Revolution against changes which they felt threatened their livelihood.
Since then, Luddite has been used to describe anyone opposed to technological progress.
Also during the programme, Mr Brunstrom discussed the concept of "parachuting politicians into safe seats".
"This issue of parachuting politicians into safe seats is a constitutional issue actually, and a sharper one here in Wales," he said.
"When one is being parachuted from Cornwall to Surrey the difference is inconsequential.
"It is still a parachute, but when you are being parachuted from England to Wales, as some of these people have been, you have to know the country you are getting parachuted into."
In a statement Mr Lucas, who was first elected Wrexham MP in 2001, emphasised his local connections which stretched back over 20 years.
He said: "To make these insulting and false comments on camera, in the full knowledge they could be broadcast, shows how atrocious the judgment of north Wales' chief officers is and how unprofessional they are.
"Neither Richard Brunstrom nor his deputy has ever had the guts to make these statements to my face."
Mr Lucas said: "I have not asked for Mr Brunstrom or Mr Wolfendale to consider their positions before, although my concerns have been mounting - but they certainly no longer have my confidence.
"It is impossible to have any type of working relationship with anyone who behaves in such an unprofessional way."
A BBC Wales spokesperson said the programme was an observational profile which followed Mr Brunstrom over a few months "and reflected his views and captured his response to issues as they happened".
"Among other issues, The Chief includes unique footage of Mr Brunstrom's reactions to the outcry surrounding his decision to show graphic photographs of a decapitated motorcyclist, and his reaction to public criticism following a press release issued by Ian Lucas MP.
"The programme was commissioned to explore the personality and motivations of one of the UK's most controversial police officers.
"BBC Wales believes that The Chief delivers this aim."
The Chief will be shown on BBC2W at 2145 GMT on Wednesday.
