The series, which stars Maxine Peake and Rupert Penry-Jones, concluded its run earlier this week after drawing average audiences of 5.9m.
Announcing the show’s return, BBC One Controller, Danny Cohen, says: “Maxine Peake has excelled in Silk and we’re delighted to be bringing this high quality, popular drama back for a second series.”
Drama Controller, Ben Stephenson, added: “Having a writer of Peter Moffat’s calibre writing a series is what drama at the BBC is all about. The audiences who have fallen in love with Martha, Clive and Billy can look forward to six brand-new cases next year.
“Now she has silk her cases will be even bigger and more dramatic – but as ever the pressure doesn’t stop there. Will Clive get silk next? Will Nick get his job? And can Kate’s Machiavellian streak ever be stopped?”
The series also stars Neil Stuke, Natalie Dormer and Tom Hughes.
