Police and Crime Commissioners: 'Tension' warning
9 November 2012 Last updated at 06:59 GMT
The introduction of police commissioners will create "inevitable tension" with chief constables over local and national policing priorities, Sir Hugh Orde has warned.
The Association of Chief Police Officers head said conflict must be resolved with "mature conversations".
Reducing crime while budgets fell was another key challenge, he told the BBC.
He spoke ahead of elections in all 41 police force areas in England and Wales outside London on 15 November.
The BBC News Channel will be in the West Midlands talking to members of the public, victims of crime and the police about the issues surrounding the upcoming elections throughout the day with Matthew Amroliwala from 09:00 GMT on Friday.
