Susanna Reid's interviewing technique received criticism during Good Morning Britain earlier today when she 'interrupted' a guest mid-flow.
Professor Paul Cosford, the Director for Health Protection and Medical Director for Public Health England, called into the studio via video chat.
The medical expert started discussing the struggle in introducing widespread coronavirus testing in the UK before Susanna interrupted to make her point.
Referring to a German science journalist who appeared on the show minutes previously, she wondered why widespread testing is taking so long to come to the UK.
