A grandfather told a court he had been to hell and back and was a shell of an individual after being poisoned with a fake Covid jab by a GP trying to murder him.
In a meticulously planned scheme, Dr Thomas Kwan disguised himself as a community nurse to inject his mothers partner Patrick OHara, 72, with a pesticide that left him fighting for his life.
Recalling his ordeal at Newcastle Crown Court, Mr OHara said the jab caused excruciating pain, and led to him being in hospital for five weeks for a series of operations.
After initially recovering he recently relapsed dramatically, losing all his hair and suffering complications including fatigue, weight loss and hallucinations.

He said: Overall, this incident should have been the end of me. The nature of what occurred to my body has left me speechless.
Had it not been for medical intervention I am positive that not only would I have lost my left arm but my life as well.
The court heard Kwan, 53, a married father and successful GP, wanted to murder Mr OHara whom he saw as an impediment to inheriting his mothers estate because he had the legal right to remain living in her flat if she died.
Prosecutor Peter Makepeace, KC, said Kwan had an obsession with money.
He had previously forged legal documents relating to the share he received in his fathers will and yet led a wealthy lifestyle
that enabled him to make an offer on a £2 million property in the south of England.
Mr OHara said despite a career as an environment analyst, working in buildings with asbestos, he had been in good health until tricked into having a Covid booster at home in January.
Kwan set up the appointment using fake NHS documents and went to his mothers flat in Newcastle disguised in a hat, mask and coat.

Mr OHara said that day my life completely changed forever.
He said: I remember that when that needle entered my arm, I felt instant, excruciating pain, I had never in my life felt anything that painful before. I instantly thought that something had gone wrong.
Mr OHara trusted the nurses opinion that it was an allergic reaction and never suspected he was his partners son Thomas in disguise.
In the days that followed he was admitted to hospital and was diagnosed with the flesh-eating bug necrotising fasciitis in his left arm.
Surgeons cut away large sections of his arm to halt the disease and he underwent two skin grafts to move skin from his thigh to his arm.
While in hospital he was in constant pain, he said.
Mr OHara said with treatment and physiotherapy he recovered well, until a sudden decline two months ago. I lost almost all my hair literally overnight, he said. I began to hallucinate in addition to numerous other ailments.
Mr OHara said his doctor believes he was suffering a delayed stress reaction. The sentencing hearing opened yesterday but will conclude at a later date.
