The Government's chief medical officer has insisted the temperature of the nurse being treated for Ebola was checked before she boarded a flight from Heathrow to Glasgow.
Dame Sally Davies told Good Morning Britain that Pauline Cafferkey "was well" at the airport.
"She had no symptoms - her temperature was within the acceptable range. She would not be transmitting the virus, therefore she was cleared as fit to fly," Dame Sally said.
"Clearly queuing and things like that are unacceptable and we will review, but we will let people who are well travel because they will not infect the public," she added.
