The World Health Organization (WHO) have found the highly infectious South African and Brazilian variants in many countries which are not on the red list.
Spain and the US could be added to the governments hotel quarantine red list to prevent new variants coming into the UK, meaning all travellers from those two countries will be forced into quarantine for 11 nights.
A government source told the Telegraph, “The US and Spain are on the list so it means some of the bigger markets will be considered by officials as part of the discussions before being put to ministers.
“It will be based on evidence from the Joint Biosecurity Centre (JBC).”
A Department for Transport spokesman said, “Our priority has always been protecting the health of the UK public, and we must now focus on ensuring the success of our vaccination programme.
“We will therefore continue taking action to lower the chances of new variants entering the UK.”
