West Yorkshire Police have announced a wide-ranging review into changes to the force to save money and improve efficiency.
Force chief constable Mark Gilmore said £64m worth of savings must be made over the next few years.
The review will look into the structure of the force while still seeking to make communities safer.
Mr Gilmore said: “Improving performance in the face of shrinking budgets is at the heart of the proposed restructure of West Yorkshire Police divisions.
“We have to find a further £64m in savings over the next three years, while delivering on the police and crime commissioner’s plan, making communities safer and feeling safer.
“That is a significant challenge and can only be achieved by making some bold, transformational changes.”
Mr Gilmore also said the force would look to work with other authorities and agencies to clamp down on crime across the area.
He said: “Our commitment is to create an even better service to the public at local level, not just from the police, but from all agencies working together as neighbourhood management teams.
“The shape of policing is changing. Challenged by reduced budgets, we are making innovative use of new technology; ensuring officers spend more time on the street and less time in the station. We are putting officers where they are needed, in the communities they serve.”
In Leeds there will be a reduction from the three police divisions to one.
The result of the review into Wakefield and Kirklees will be announced later this year.
