"Devil" nurse Victorino Chua has maintained his innocence after being jailed for 35 years for murdering and poisoning patients at Stepping Hill Hospital.
In a statement issued by his solicitor, Chua said: "I am completely innocent of any wrongdoing. I now face a minimum of 35 years in custody for crimes I did not commit."
He vowed to fight to prove his innocence, and said he had "every sympathy" with the victims who had been failed by the "wrongful conviction".
Chua, 49, was branded a narcissistic psychopath by police, was sentenced for two murders and 20 other poisonings at Manchester Crown Court yesterday.
He did not show a flicker of emotion as he was told he would be in his 80s before he can apply for parole.
But today he reiterated his claim of innocence, dismissing the evidence heard during the trial as "circumstantial".
He said: "I continue to deny that I was the perpetrator of the insulin poisoning and prescription chart alteration offences at Stepping Hill Hospital in 2011 and 2012.
"I am completely innocent of any wrongdoing. I now face a minimum of 35 years in custody for crimes I did not commit."
Chua's trial heard that, during his random poisoning spree, Chua "left it to fate" as to which patients would live or die.
The father of two secretly injected insulin into saline bags and ampoules which were then used unwittingly by other nurses at the hospital in Stockport, actions which the judge, Mr Justice Openshaw, described as "indescribably wicked".
Chua received 25 life sentences in total and will be aged 84 before his 35-year minimum term expires and he is eligible for parole.
