More than 500,000 official "spying" requests for private communications data such as telephone records were made last year, a report says.
Police, security services and other public bodies made requests for billing details and other information.
Interception of Communications Commissioner Sir Paul Kennedy said 1,707 of these had been from councils.
A separate report criticises local authorities for using powers to target minor offences such as fly-tipping.
