Shapps confirmed to BBC Radio 4’s Today programme on Thursday (20 May) the list would be reviewed, for the first time, in early June.
However, while stressing he was personally pushing for the list to be extended, he reiterated the government’s stance that this would likely depend on "other countries catching up" with the UK’s vaccination programme.
"That’s going to gradually happen, you can see it’s happening, so that list should expand," he said. "We’re reviewing this all the time, every three weeks – the next review is in the first week of June and we’ll have to see what happens.
