Warwickshire Police to cut almost 400 jobs
Almost 400 jobs are expected to go at Warwickshire Police by 2015, according to HM Inspectorate of Constabulary.
The force has said it is facing a budget cut of £22.9m over the four years until 2015.
It has already agreed to form a "strategic alliance" with West Mercia. Both will retain chief constables accountable to their authorities.
The figures detailing the proposed job cuts were supplied by the force to HMIC last month.
Up to 355 police officers and staff jobs are likely to go, along with 22 PCSOs, the figures show.
Overall, HMIC has estimated more than 30,000 police jobs - 16,200 officers and 16,100 civilian staff - will go in England and Wales by March 2015.
The organisation carried out an inspection of all 43 forces and authorities in England and Wales earlier this year to look at how they are dealing with budget cuts.
A spokesman for HMIC said Warwickshire Police "clearly understood the scale of the financial challenge".
"At the time of its inspection, plans were in place to make £13.5m of savings by 2013-14 [year three of the comprehensive spending review period], which is 59% of the total financial requirement.
"The outstanding gap is significant and the force and authority have realistically acknowledged that service reduction may be required to make up the remaining £9.4m if savings cannot be found within the strategic alliance with West Mercia Police."
Confirming the alliance last month, the forces said agreed recommendations would enable them to meet the challenge of reducing policing budgets.
The recommendations would enable both forces to "provide greater operational and organisational resilience".
The framework had been signed off, but the detail was still to be worked out, they added.
