Stephen Reicher, professor of psychology at the University of St Andrews, and one of Ms Sturgeon's hand-picked advisers has said that the increase in vaccination rates in Scotland was "exactly the same as in England where they didn’t have passports”.

       Professor Reicher, who sits on the Scottish Government’s COVID-19 Advisory Group, instead warned that the policy could backfire by reaffirming the view held by some vaccine sceptics that jabs are about controlling people.

       Ms Sturgeon will announce later today whether the scheme will be extended to cinemas, theatres and other hospitality venues.
