Summer holidays: Which countries are on the red, amber and green travel lists?
After over a year of lockdowns and restrictions, many are desperate to leave home and go abroad for some much-needed escapism.
But before anyone books a holiday, they should check the traffic light system, which sets out the rules travellers need to abide by when returning from each destination.
The latest changes, announced on Thursday, have just come into force. The list has been criticised by many, including travel industry leaders and groups representing passengers rights. Labour says the government has "caused chaos with the mishandling of travel restrictions at the border".
Here are the new countries that have been added to the red, amber and green lists as of Monday 19 July at 4am BST.
Watch: Countries on the UK green list
Green list
The following countries are new additions to the green list:
Bulgaria
Croatia
Hong Kong
Taiwan
Croatia and Taiwan will also be added to the green watchlist. This means these countries are potentially at more risk of moving from green to amber at short notice if cases start to rise.
If you are coming back from a green list destination, you still have to provide proof that you have tested negative for COVID before you travel and take another test on the second day after you land.
Amber list
The following countries are new additions to the amber list:
Balearic Islands (previously on green list)
British Virgin Islands (previously on green watch list)
For these to have moved from green to amber is frustrating for those who had booked holidays there.
Boris Johnson has previously said: "I think it's very important for people to grasp what an amber list country is: it is not somewhere where you should be going on holiday, let me be very clear about that."
Other rules to be aware of include changes for those who have been double jabbed.
From 19 July, if travellers come back from an amber list countries and have been fully vaccinated for at least 14 days, they will no longer need to quarantine or take a test on the eighth day of being back in the country. This only applies to those who have had their jabs via the NHS.
France has also been made an exception to this rule, with even double vaccinated travellers needing to self-isolate after returning.
You must be able to provide proof of your vaccination status to before coming back to England. This will also apply to people on a formally approved UK COVID-19 vaccine clinical trial and children under the age of 18 from 4am BST on Monday 19 July.

If you have not had both vaccines...
Non-vaccinated passengers arriving from amber countries need to provide evidence of a negative test result prior to travel, self-isolate at home for 10 days, and take a test on the second and eight day after arrival. As before, you will also have the option to take a further test on day five and end your 10-day self-isolation early, if you test negative.
