A neo-Nazi who plotted to kill Labour MP Rosie Cooper has been jailed for at least 20 years.
Jack Renshaw, 23, bought a 19-inch (48cm) knife to kill the West Lancashire MP and exact revenge on a female police officer who was investigating him for child sex offences.
He also Googled "how long to die after jugular cut" and researched Mrs Cooper's schedule as he formed the plot.
The plan was thwarted by whistleblower Robbie Mullen, who was at a meeting in a pub when Renshaw announced his intentions in July 2017, one year after Labour MP Jo Cox was murdered.
Renshaw, from Skelmersdale, Lancashire, was sentenced to life with a minimum term of 20 years at the Old Bailey on Friday after he admitted making preparations to kill his local MP and making a threat to kill police officer Victoria Henderson.
Renshaw raised his arm in an apparent Nazi salute as a supporter in the public gallery shouted "we're with you Jack" while he was led away.
Sentencing Renshaw, Mrs Justice McGowan said: "Your perverted view of history and current politics has caused you to believe it right to demonise groups simply because they are different from you."
She added: "This is a case in which only a sentence of life imprisonment can meet the appalling seriousness of your offending."
In a statement after the sentencing, Mrs Cooper said: "My deepest wish is that this case is the last occasion when any public servant, any politician, has their life threatened for simply doing their job.
"I believe today justice has been served. Not for me personally, but for every MP and public servant, and for our democratic way of life which affords us the privilege of free speech, without fear of violent retribution."
In a victim impact statement read by Duncan Atkinson QC, prosecuting, the MP said the plot against her was like "something out of a horror movie" and caused some of her staff to leave their jobs.
Renshaw announced his plan at the Friar Penketh pub in Warrington at a meeting with the leader of banned extremist group National Action, Christopher Lythgoe, and others including Mr Mullen.
Mr Mullen, from Widnes, Cheshire, shared details of the plot with campaign group Hope Not Hate.
