Questions are being asked about how appropriate it is for Avon and Somerset Police's new Chief Constable to take his position.
When Andy Marsh starts in February, he will be making policing history. ITV News understands this is the first time in Britain a Chief Constable been married to another member of the same force's command team.
His wife is Assistant Chief Constable Nikki Watson.
The Police and Crime Commissioner Sue Mountstevens says a policy will be put in place to make sure he does not line-manage his wife. And if ACC Watson needs to be disciplined, that will be conducted by a chief of another force. Not her husband.
But some police experts say this set-up could lead to questions over objectivity and favouritism.
Neither Mr Marsh - who is currently Chief Constable at Hampshire Police, nor ACC Watson, wanted to comment.
This move comes after much turbulence over the top job at the force.
- In 2012 Sue Mountstevens was elected Police and Crime Commissioner.
- Soon after, the long-standing Chief Constable Colin Port resigned then took her to court, losing the case.
- Nick Gargan started in March 2013 but was later suspended and found guilt 8 counts of misconduct.
- Gareth Morgan has been temporary chief, but he was overlooked last week in favour of Andy Marsh.
But Andy Marsh's appointment brings this unique set-up.
Lawrie Lewis, a Retired Assistant Chief Constable at Avon & Somerset Police, said he had come across both Mr Marsh and his wife during his career, and doesn't believe their relationship would hinder their jobs.
