BBC One has had a strong year, achieving its best peak time share since 2008, and fueled by such series as Call The Midwife, Poldark, Doctor Foster, The A Word, Luther and the Sherlock special. At the Edinburgh TV Festival today, BBC Director of Content Charlotte Moore unveiled a slate of six new series including divorce-lawyer drama The Split from Emmy-winner Abi Morgan and exec produced by Broadchurch‘s Jane Featherstone. Moore also revealed that Thandie Newton has been set to star as the guest lead in Season 4 of Jed Mercurio’s Line Of Duty.

Speaking at the fest, Moore credited risk-taking and innovation for BBC One’s recent success. She also promised the flagship network will “continue to challenge what mainstream television means and connect with an increasingly diverse UK.”

Details on the new commissions are below:
