What happened to Robbie Mullins?
After the plot was exposed, Jack Renshaw was sent to prison for life in 2019 having admitted to preparing to kill Rosie Cooper and making threats to kill a police officer.
Robbie, who is played by Andrew Ellis in the ITV drama, continued to attend National Action meetings so that he didn't blow his cover as the informant.
He also gave further evidence against other group members before he was outed as a mole.
In an interview with The Observer, the former warehouse worker revealed that he had turned down the police's offer of witness protection. "The police have offered me witness protection after each death threat but each time I’ve turned it down because I want the option to go back home," the Warrington resident said. "They would have made me start again, changed my name."

"Written by Oscar-nominated and BAFTA multi-award-winning screenwriter, Jeff Pope, the drama is an explosive state-of-the-world series that explores some of the most critical and relevant issues of modern times including racism, freedom of speech and terrorism.
"It's a thought-provoking, conscience-stirring drama which poses timeless questions - What makes people fear and hate those who are different from themselves? Can someone’s view of the world be fundamentally changed?"
