The critically acclaimed thriller, which also stars Jack Lowden, Kristin Scott Thomas, Jonathan Pryce, and Saskia Reeves, has released a logline for season seven, revealing that Lamb and his Slow Horses will be "on the hunt to find and neutralise a mole at the heart of British Government before they can bring down the state."

Before Slow Horses came out, Kristin Scott Thomas didn't really enjoy watching television. That was not too long ago.

Of Down Cemetery Road, Herron said: "It stars Emma Thompson and Ruth Wilson. Morwenna Banks has written the series, and she's done a wonderful job. There's quite a lot of overlap in the teams that made Slow Horses and Down Cemetery Road, and what I've seen of it, which is only little bit, is looking absolutely tremendous."
