Top UK scientist Sir Jeremy Farrar is to be questioned by the US Congress amid questions of the origins of the coronavirus that causes Covid 19.
Sir Jeremy, an expert in tropical diseases, is head of the Wellcome Trust, which gives millions of pounds to medical research every year and is a former member of Government scientific advisory group SAGE.
He was initially among a group of scientists who said the Covid virus could have come from a lab in Wuhan, reports the Mail.
