A Chinese whistleblower claims she has proof that the coronavirus was created in a lab in Wuhan – after previously claiming Beijing had covered up the outbreak.
Dr Li Meng-Yan, who is a researcher at the Hong Kong School of Public Health, says she was among the first to study the deadly virus when it first emerged last year.
And she claims a supervisor even told her “we will get in trouble” if they spoke out over the deadly virus which she was created in a Wuhan lab.
But this theory has been challenged by experts, with the official organisation healthfeedback.org writing: "The genetic features of SARS-CoV-2 are common in other coronaviruses that occur in nature and have animal reservoirs.
"Therefore, these features do not prove in any way that the virus was constructed in a laboratory or genetically modified."
It goes on: "The author does not provide evidence to support her claim that the virus causing COVID-19 was created in a lab."
Dr Meng-Yan featured on Loose Women on Friday where she offered even more information about the virus.
She said: "The genome sequence is like a human fingerprint. Based on this you can identify these things.
“I will (use this) evidence to tell people why this has come from the lab in China, why they are the ones who made it.
"Anyone, even if you have no biology knowledge, will be able to read it, and check and identify and verify it yourself."
Dr Meng-Yan escaped to the USA from Hony Kong earlier this year amid allegations that Beijing had attempted to silence her.
She had previously suggested the virus had escaped from a People's Liberation Army (PLA) facility.
She explained that Chinese authorities had tried to discredit her before she had even escaped China to tell her version of events.
She claimed: “They deleted all my information and also they told people to spread rumours about me.
"That I'm a liar, I don't know anything, I just killed a hamster in the lab.
“They will try to control my family and friends and then suddenly I don't exist."
