Johnson said changes to testing for international travellers who are fully vaccinated will be made now Britain is "moving through the Omicron wave".
Speaking to broadcasters during a visit to Milton Keynes Hospital, he said: "So what we’re doing on travel, to show that this country is open for business, open for travellers, you will see changes so that people arriving no longer have to take tests if they have been vaccinated, if they have been double vaccinated."
