Senior cabinet ministers are to discuss allowing fully vaccinated travellers from the EU and US to avoid quarantine when they arrive in England.
A review of the border rules is due by 31 July – the second date in the Department for Transport’s plan for a safe return to international travel.
Sources said the isolation exemption was likely to be discussed at the Covid Operations meeting on Wednesday.
But they said a decision on whether to proceed will not necessarily be taken.
Currently, people who have been fully vaccinated in the UK do not have to quarantine when travelling from the US and EU, apart from France, because those places are on the amber list (and some EU countries are on the green list). But that exemption does not apply to people who have been vaccinated outside the UK.
Downing Street and the Department for Transport declined to comment on newspaper reports the government would go ahead with the plan to also exempt people vaccinated in the US and EU.
“At the moment we’re in this slightly ridiculous situation where if I’m on a plane from Spain, because I’m lucky enough to have had two jabs, once we get to the UK I just wander off, no problem,” said travel expert Simon Calder.
“But the person sitting next to me, who happens to have had their vaccinations in Spain, not in the UK, has to go and sit in a room for 10 days. Doesn’t make sense.”
