Muhammad Rodwan, 56, has been jailed for 16 years with a further three years on extended licence for a “brutal and shocking” machete attack on PC Stuart Outten.
PC Outten suffered multiple stab wounds and skull fractures when his attacker struck him with a 2ft long blade in east London on the evening of August 7 last year.
Bleeding heavily from six deep gashes to the head and one to the arm, PC Outten managed to Taser Rodwan twice and brought him to the ground, the Old Bailey heard.
The incident happened when the 29-year-old Metropolitan Police officer and colleague PC Helen Brooks pulled over Rodwan's white van for having no insurance.
PC Stuart Outten suffered stab wounds and skull fractures
Jurors, who were not told of Rodwan's previous convictions for two machete attacks and rape, deliberated for seven hours before finding him guilty of wounding with intent at the same court yesterday.
He was cleared of attempted murder and possession of an offensive weapon.
Rodwan had denied the charges against him and claimed he was acting in self-defence.
He told police: "My life is worth more than his life".
Muhammad Rodwan has been sentenced to 16 years behind bars
Judge Mrs Justice Carr today said that "arrogant" Rodwan had picked up the freshly sharpened machete "in a rage" as she handed him the sentence.
She said: "This was a brutal and shocking attack with a machete on a police officer carrying out his duties during what should have been a routine stop of a van to investigate whether you were properly insured.
"I'm sure the violence started with you when PC Outten blocked your attempt to close your door.
"I reject the unattractive submission that he was using excessive force in circumstances when you had assaulted him and forcibly resisted arrest."
The judge added: "I detect not a shred of remorse or insight on your part, but rather belligerent arrogance, typified by your comment when charged that your life was worth more than that of PC Outten."
