The UK's traffic light system for international travel could change next month.
Currently, requirements vary depending on whether someone is arriving from a green, amber or red location, and whether or not they are fully vaccinated.
The lists are updated every three weeks, with the next changes due next week.

But a wider overhaul of the rules is scheduled to take place by October 1.
Rumours suggest the traffic light system could be scrapped on this date.
Speaking on his travel radio show, Simon Calder said: "I think we might see the traffic light system effectively-being scrapped, particularly with thankfully vaccination rates in the UK now being so high.
“It will just be assumed that everyone is vaccinated and therefore wherever you are going, perhaps with a relatively small list of places, you won’t need to quarantine.”
It comes as British Airways chief executive Sean Doyle said rules relating to coronavirus testing and quarantine for arriving travellers must be simplified.
Mr Doyle said Government policy is "the biggest single enabler" of airlines recovering from the virus crisis.
He went on: "We had the traffic light system over the summer.
"There was some progress made.
"But I think it's not fit for purpose.
"It needs to be simplified.
"It needs to be adapted in the same way that we see in Europe and in the US."
He added: "We'd encourage the Government to look at seizing that opportunity in the next few weeks.
"Aviation needs the same crack of the whip economically as other sectors are getting domestically.
"We're not at the minute under the current system."
