Kosminsky said: “The series is based deep within the least-known arm of the UK’s intelligence infrastructure, GCHQ.

“The story we’re now able to tell casts an extraordinary, revelatory light on the hot, undeclared war taking place right now in the world’s newest and most invisible domain of conflict – cyber.”

Caroline Hollick, Channel 4’s head of drama, said: “Peter Kosminsky is a titan of British television drama, and it’s a privilege to have this ground-breaking thriller on Channel 4 – it’s a truly momentous series which will change the way we see the world around us.

“I’m also delighted to have such stellar names in the cast, as well as the chance to break brand new on-screen talent.”
