A senior official from the US Department of Health, who conspired with Anthony Fauci to downplay suggestions Covid-19 leaked from a Wuhan laboratory, says the lessons from the outbreak haven’t been learnt and warns of the chance of another pandemic emerging from high-risk experiments.

The health official who conspired with Anthony Fauci to downplay suggestions Covid-19 leaked from a Wuhan laboratory has revealed he lies awake at night agonising about the chain of events they set in motion.

The former Assistant Secretary for Preparedness and Response at the US Department of Health, Dr Robert Kadlec, has told Sky News he feels obligated to reveal confidential discussions he had with Dr Fauci, America’s top infectious diseases adviser, about diverting attention away from the lab leak theory.

In his first television interview, to air on Sky News on Tuesday night, he also warns of another pandemic emerging from high-risk experiments in laboratories globally, saying the lessons from Covid-19 haven’t been learnt.
