COBRA: Cyberwar Sky Showcase, 9pm

Robert Carlyle (below) returns as British Prime Minister Robert Sutherland, who is still dealing with the aftermath of the first series when he's hit by cyber attacks and subversive fake news. In the opening episode, Sutherland feels he has no choice but to respond with force to a suspected

Kremlin operation. But that means going against the head of MI5. ★★★★★
