Boris Johnson has given his clearest hint so far that vaccine passports are likely to be required for international travel.
His comments were made after politicians including Jeremy Corbyn and Sir Ed Davey warned against the introduction of the certificates on the grounds that they would be “divisive and discriminatory”.
The Prime Minister said that they would definitely have a role to play when international travel resumes. “On the issue of vaccine certification, there’s definitely going to be a world in which international travel will use vaccine passports”.
