Foreign Secretary Dominic Raab told LBC radio that the government is considering a domestic scheme to allow greater freedoms to those who can prove they have been vaccinated.

"It's under consideration, but of course you've got to make it workable," Raab stated:

"I'm not sure there's a foolproof answer in the way that sometimes it's presented, but of course we'll look at all the options," Raab added.

Raab's comments come after vaccines minister Nadhim Zahawi declared last month that any form of vaccine passport would be 'discriminatory'.

A senior government source also told the Telegraph that the Government has been "very cautious about this idea that if you don't have a passport therefore somehow your liberties are curtailed".
