Ed Balls: Police commissioners plans 'a waste of money'
The cost of introducing police and crime commissioners could reach more than £136m over 10 years, government documents show.
The elected officials overseeing forces in England and Wales outside London would be paid about £122,000 a year.
The 43 police forces are facing cuts of between 14% and 20%.
Shadow home secretary Ed Balls has attacked the plans as a "waste of money" and called on the government to "think again".
