Will Sharpe will return as idealistic rookie barrister Will Packham, who is learning his trade from Humans star Katherine Parkinson’s Caroline, a cynical, worldly-wise pupilmaster.
Mark Bonnar (Catastrophe), Gwyneth Keyworth (Black Mirror) and Prasanna Puwanarajah also star in the show.
The comedy is written by Kieron Quirke, who wrote Cuckoo, and is based on the book Defending The Guilty: Truth And Lies In The Criminal Courtroom by Alex McBride.
Big Talk CEO Kenton Allen, Saurabh Kakkar, and Quirke are the executive producers for the ITV Studios-owned indie, while Kate Daughton is the executive producer for the BBC. Jim Field Smith is the co-executive producer.
The six-part second series was commissioned by BBC comedy controller Shane Allen, Daughton and Patrick Holland, the controller of BBC Two.
