Jurors were told the manifesto found on the former supermarket worker’s mobile phone read: “They’ll call me a terrorist, they’ll call me an extremist: I’m neither.

“Be the white man they say you are. Be the revenge of Albion. Be the wrath of Britannia.”

Some of the defendant’s tweets also advocated extreme violence against immigrants entering Britain; One stated: “Open the door with a knife in your hand and shout at them. If they attack you, it’s fair game.”

Hitler’s signature

Jurors were told Parslow had Hitler’s signature tattooed on his arm “to show his devotion to the ideals of the German Nazi party leader”.

Explaining the circumstances of the attempted murder to the jury, Mr Storey said: “Mr Hagos (after being asked by Parslow where he was from) told him he was Eritrean.

“The defendant then produced a knife and continued to stab and attack her, causing wounds to her chest and the back of her hand.

“The defendant’s actions that day were carefully planned and guided by a particular ideology, particularly a far-right ideology, which led him to identify and target his victim based on his ethnicity.”

‘God saved me’

Mr Hagos was eating at the conservatory when he was attacked, and said of his survival: “I still look at it as a miracle. God saved me.”

At the start of the hearing, Mr Storey, who prosecuted the case on behalf of the Crown, said: “In the weeks before this incident, the defendant had planned what he would do and had investigated hotels used to house asylum seekers on behalf of the government.”

The jury heard he also researched the “worst places to be stabbed” and whether neck wounds were always fatal.

Describing the manifesto Parslow planned to publish immediately after the stabbing, Mr Storey said it began: “I have only done my duty to England” and continued: “I am nothing but a gardener tending the great garden of England.”

Mr Storey said: “In his mind the mission was the murder of an asylum seeker, someone who had fled his country for whatever reason and hoped to make a life for himself here.

“The motivation for his attack was said to be his desire to be arrested due to being evicted from his home after losing his job.”

CCTV footage of the stabbing and its aftermath showed Mr Hagos, clearly bleeding and in distress, fleeing into a car park and being chased by Parslow.
