It has been announced that David Walliams will star in a new BBC Agatha Christie adaptation. 

The comedian is to star in a six-part series, Partners in Crime, which is based on two Agatha Christie books, The Secret Adversary and N or M.

42-year-old Walliams, who penned the adaption will take on the role of one half of the married detective duo Tommy and Tuppence.

Speaking about the project Walliams said: "In bringing these thrilling stories to the screen, it is our ambition for Tommy and Tuppence to finally take their rightful place alongside Poirot and Marple as iconic Agatha Christie characters." 

The adaptation is the first of several Christie programmes scheduled to appear on the BBC, to celebrate the author's 125th anniversary of birth. A series of documentaries about the famous crime writer - who died in 1976 - are also in the pipeline to mark the occasion.

Later in 2015, the channel will show a three-part adaptation of And Then There Were None adapted by Sarah Phelps.
