Peter Davison Joins The Cast Of LAW & ORDER: UK

Former Doctor Who star Peter Davison will begin appearing as a regular cast member of Law & Order: UK, the Doctor Who News Page reports.  He will join Doctor Who alumna Freema Agyeman on the series.

"Filming begins shortly on the next series of the UK produced show based on the NBC Series. Davison will play Henry Sharpe, the man taking over the job of Director of the CPS, described as a down to earth pragmatist and a great boss. Returning to the series is Freema Agyeman, who played Martha Jones in Doctor Who." 

Law & Order: UK airs on ITV1 in the UK and is currently being shown on BBC America.

Here's a little bit of background on the series premise from Wikipedia:

"Law & Order: UK (also known as: Law & Order: London in Ireland) is a member of the Law & Order franchise, one of the most successful brands in American primetime television.

Law & Order: UK is based in London and duplicates the episode format of the original series. The first half focuses on the perpetration of a crime and the related police investigation typically culminating in an arrest, while the second half follows the legal and court proceedings in an effort to convict the suspect. The show dwells little on the characters' back-stories or social lives, focusing mainly on their lives at work."
