A NEONAZI could face a life behind bars for plotting the murder of Labour MP Rosie Cooper while under investigation for grooming young boys for sex.

Jack Renshaw, 23, bought a 19in Gladius knife to kill the West Lancashire MP and exact revenge on a female police officer who interviewed him, the Old Bailey heard.

The plan was scuppered by whistleblower Robbie Mullen, who was at a meeting in a pub when Mr Renshaw announced that he was going to kill Ms Cooper in July 2017.

Mr Mullen, 25, began leaking information about National Action to anti-fascist campaign group Hope Not Hate.

It came just a year after Labour MP Jo Cox was stabbed and shot by fellow far-right extremist Thomas Mair.

Mr Renshaw, from Skelmersdale, Lancashire, had admitted making preparations to kill his local MP and issuing a threat to kill police officer Victoria Henderson.

But he denied membership of banned neonazi group National Action, as did Andrew Clarke, 34, and Michal Trubini, 36, from Warrington.

A jury at his retrial was discharged, having failed to reach verdicts after more than 48 hours of deliberations and prosecutor Duncan Atkinson QC said he could not seek a third trial.

It can now be reported that Mr Renshaw is a convicted paedophile who was jailed last June for 16 months after he groomed two underage boys online.

Jurors at Preston crown court found him guilty of four counts of inciting a child to engage in sexual activity.

He also received a three-year prison sentence two months earlier when he was convicted of stirring up racial hatred after he called for a genocide of Jewish people.

A spokesperson for north-west England anti-fascist organisation 0161 Manchester, which was heavily involved in efforts to stop Mr Renshaw establishing a Manchester Young BNP branch several years ago, told the Star: “The correlation between Jack Renshaw’s paedophilia and his neonazism should come as no surprise.

“Jack was an attention-seeker who engaged in seedy, vile fantasies about killing Jewish people and anti-fascists.

“However, he was never a confident nazi in person and would hand over his BNP leaflets and rosettes to anti-fascists and community activists with regularity.

“Every decent thinking person in the north will be glad to see the back of him.”

Ms Justice McGowan remanded Mr Renshaw into custody to be sentenced on May 17.
