What are the holiday rules for travel to green, amber and red list countries?

People fully vaccinated in Europe or the US no longer need to isolate when arriving in the UK from an amber country.

France is still excluded however, because of concerns about the Beta variant.

People fully vaccinated in the UK don't need to isolate when arriving from an amber country.

This has been extended to those jabbed in the US and EU nations, plus Norway, Iceland, Switzerland, Liechtenstein, Andorra, Monaco and Vatican City.

Meanwhile, a proposal for an "amber watchlist" of countries at risk of moving to red has been scrapped, government sources told the BBC.

The vast majority of countries are on the amber list.

Adults fully vaccinated in the UK, the US and most European countries don't have to self-isolate upon arrival in the UK.

France is an exception, with 10 days quarantine required. This is because of concerns about cases of the Covid Beta variant.

A Covid test is needed three days before returning from an amber country, and a PCR test two days after arriving.

Adults can prove they were vaccinated at least 14 days previously, via the NHS Covid Pass, or an NHS Covid Pass letter in England, and equivalents in the rest of the UK.

Under-18s do not have to self-isolate. In England, Wales and Northern Ireland, children aged 10 and under don't have to test before travel, but do need to take one two days after arrival. Those aged four and under don't need any tests.

In Scotland, children over 12 have to take tests before returning home, and on day two.

There are only a handful of destinations - including Madeira, Croatia and Malta - on the green list. Nobody has to self-isolate after visiting them.

Returning from a green-list destination, you must:

You only need to self-isolate on return from these countries if your day two test is positive, you develop symptoms or NHS Test & Trace says you've travelled with someone who tested positive.

Red list countries are those the UK government says present the highest Covid risk, and should not be visited "except in the most extreme of circumstances".

Dozens of countries are on the red list, including India, Pakistan, Turkey, Brazil and South Africa. If you have been in one in the last 10 days, you can only enter the UK if you are a UK or Irish national, or UK resident.

Returning from a red-list country - regardless of your vaccination status - you must:

Rates are:

All countries go on the amber list unless there is evidence to suggest they should be on the green or red lists.

Ministers make the decision, based on advice from the Joint Biosecurity Centre (JBC), which looks at the Covid situation in each country.

The lists are reviewed every three weeks and the system is similar for England, Scotland, Wales and Northern Ireland.

It is your responsibility to check the entry rules for your destination, which can change at short notice. Some countries only allow fully vaccinated visitors, or insist on a quarantine period.

The UK Foreign Office (FCO) provides detailed country-by-country advice.

Before returning to the UK you need to pay for a private test with high accuracy, such as a PCR or antigen test. Further tests may be required after you return.

In the UK, tests can be bought from approved providers. You can also find lists of providers in some destinations on UK government travel pages.
