US television network Starz has decided not to give Kelsey Grammer another term as mayor of Chicago.

The cable network has announced it is cancelling the drama Boss after two seasons.

The show premiered to critical acclaim, starring former Frasier star Grammer as tyrannical Chicago mayor Tom Kane.

The role earned Grammer a Golden Globe for best actor in a drama earlier this year.


Starz says in a statement that although the network is proud of the show, it has "made the difficult decision to not proceed with Boss".

The move was a flip-flop for the network, which renewed the show for a second season even before its first season began.

Boss also stars Martin Donovan, Connie Nielsen and Kathleen Robertson.

Farhad Safinia is the show's creator and executive producer.
