The government has recently announced that Spain is no longer listed as one of the countries exempt from quarantine.
Due to a spike in coronavirus cases, those travelling back from the country will once again face a 14 day period of self-isolation when they return to England.
The U-turn has highlighted the government's willingness to reverse or re-implement coronavirus measures as the situation changes.
Brits can currently travel to 79 countries without having to quarantine when they get back to England.
But the scheme is not reciprocal, and not all of those 79 countries are currently welcoming British tourists.
So what countries are still quarantine-free for travellers when returning back to England - and which of these have opened their borders to British holidaymakers?
Countries that have opened their borders to Brits -and are quarantine-free on return
Regular flights are beginning to resume to a number of popular quarantine-free destinations, including Italy, Poland, Norway, the Netherlands, Malta, Greece, Germany, France and Croatia.
Tourists travelling to these countries will not need to quarantine when they arrive on their holiday, or when they get back to England.

Entry into Switzerland, Denmark, Liechtenstein, Czech Republic, Austria and Slovenia is also permitted for British nationals, and will not require quarantine on arrival or return to England.
Slovakia, Estonia, Lithuania, Belgium, Vatican City, Monaco and Luxembourg have all re-allowed entry into the country for travellers from the UK.
There are no longer any coronavirus related restrictions on entry to San Marino, but visitors must comply with social distancing measures.
Turkey reopened its borders in June, but passengers may be subjected to health checks on arrival.
The Turks and Caicos Islands have been open to visitors as of 22 July, but travellers must obtain pre-travel authorisation that requires evidence of a negative Covid-19 test.
South Korea is quarantine free on return to England, but all passengers regardless of nationality must undergo checks and a two-week period of quarantine on arrival in South Korea.
Those travelling to Ireland will be expected to quarantine for 14 days, unless they are travelling from Northern Ireland, or meet one of the other exemptions based on their work status.
Passengers arriving in Iceland can either pay for a coronavirus test or undergo a two-week period of quarantine.
St Pierre and Miquelon, St Lucia, St Helena, Ascension and Tristan da Cunha, St Martin and St Barthélemy, Seychelles, Reunion, New Caledonia, Latvia, Jamaica, Hungary, Guadeloupe, Grenada, Gibraltar, French Polynesia, Curacao, Bermuda, Aruba, Antigua and Barbuda, Andorra, Barbados and the Falkland Islands are also open to travellers but will incur some further entry requirements, health checks or a period of quarantine on arrival.
Countries exempt from quarantine when arriving in England - but remain closed to UK nationals
New Zealand and Australia are currently closed to almost all international arrivals, but are listed under the UK government’s quarantine-free arrivals list.
This means you can travel from New Zealand or Australia into England, but not the other way around.

Vietnam is closed to transit passengers, and has temporarily suspended entry into Vietnam for all foreign nationals.
Finland’s borders also remain closed to non-resident foreign nationals.
Foreign nationals are only permitted to enter Taiwan provided they are not entering for study, tourism or to visit friends, thus ruling out holidays for Brits.
Foreign travellers attempting to visit Hong Kong or Japan will also be denied entry.
Trinidad and Tobago, St Vincent and the Grenadines, St Kitts and Nevis, Pitcairn Island, Montserrat, Mauritius, Macao, Fiji, Dominica, Cyprus, Cayman Islands, British Virgin Islands, Bonaire/St Eustatius/Saba, Bahamas, Anguilla, South Georgia and the South Sandwich Islands are exempt from quarantine when arriving in England, but are all closed to British tourists.
