Sir Patrick Stewart's sitcom 'Blunt Talk' has been axed after two series.

The 76-year-old actor's show - which followed British newscaster Walter Blunt, who was portrayed by the 'X-Men' star, as he aims to takeover cable news in the US - has been shelved by Starz following a 20-episode run.

The show was created by Jonathan Ames and executive produced by Seth Macfarlane.

Carmi Zlotnik, president of programming at Starz, said in a statement: ''We are grateful to Jonathan and Patrick for the tirades and laughs that Walter Blunt delivered to fans with such aplomb.

''While Walter may not be returning to the airwaves, we are incredibly proud of the work that was done these past two seasons by our wonderful partners and collaborators on 'Blunt Talk,' from Seth MacFarlane and our studio MRC, to our actors, writers and crew.

''It was a very special show with a heartfelt message. It was an honour serving you, Major.''

While the reasons for the axing have not been confirmed, it is believed to be due to a struggle to find an audience.

Starz initially ordered 20 episodes of the series which were divided into two series.

The first season began in August 2015 and the second premiered on October 2, 2016 before concluding on December 11, 2016.

Walter Blunt's name was taken from his namesake in William Shakespeare's 'Henry IV, Part 1', which was Patrick's first role with the Royal Shakespeare Company.

Jacki Weaver, Adrian Scarborough, Dolly Wells and Timm Sharp also appeared in the sitcom, and Moby guest starred.
