A map of the local authority boundaries for Great Britain. Each local authority has id set to the local authority code and title set to its name.
The data to create the map was obtained from the Ordinance Survey and remains theirs by (C). However, they permit usage under the open government license v3 (http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/), which I believe to be permissive.
