A man who plotted the murder of an MP will not face a retrial for membership of a banned neo-Nazi group.
Jack Renshaw, from Skelmersdale in Lancashire, bought a machete to kill Labour’s Rosie Cooper and a police officer against whom he had a grudge.
The 23-year-old admitted preparing an act of terrorism but denied membership of National Action.
After a seven-week retrial, the Old Bailey jury said it was unable to reach a unanimous or majority verdict.
It can now be reported for the first time that Renshaw was last year convicted of grooming two adolescent boys online for sex.
During the first Old Bailey trial last year, he admitted a terrorist plot to murder Ms Cooper with a 19in (48cm) Gladius knife.
He also pleaded guilty to making a threat to kill detective Victoria Henderson, who was investigating him for sexual offences.
Renshaw’s terrorist plot was foiled after a whistleblower – former National Action member Robbie Mullen – warned the anti-racism charity Hope not Hate, which then informed police.
The retrial jury was also unable to decide whether Andrew Clarke, 34, of Prescot, Merseyside, and Michal Trubini, 36, of Warrington, Cheshire, remained members of National Action after it was proscribed in December 2016.
The British group, founded in 2013, was banned three years later under anti-terror laws.
Jurors, who had deliberated for more than 48 hours, have been discharged.
The prosecution said it would not be seeking a third trial.
