Police workforces will be cut by 32,400 officers and staff by March 2015, including the loss of at least 15,000 officers, the HMIC report said.
Some 2,700 officers were lost from the frontlines by March this year, and this will increase to 5,800 (6%) by March 2015.
The total frontline workforce will also be cut by 8,100 officers and staff, or 6%, while those in non-frontline functions will see the loss of 20,300 officers and staff, a third of the total.
Neither the Met nor Cheshire could provide detailed figures of how the cuts will affect their frontlines.
