Unitary Authorities
A unitary authority is a type of local authority that has a
single tier and is responsible for all local government functions
within its area or performs additional functions which elsewhere in
the relevant country are usually performed by national government
or a higher level of sub-national government.
Typically unitary authorities cover towns or cities which are
large enough to function independently of county or other regional
administration. Sometimes they consist of national sub-divisions
which are distinguished from others in the same country by having
no lower level of administration.
Carlisle City Council is not part of a unitary authority.
