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

More countries are moving to the travel green list on Sunday.

Rules for fully-vaccinated passengers arriving from France will also change.

Changes come into force at 04:00 BST on Sunday.

Amber list rules will apply to France, for fully vaccinated passengers arriving in England, Scotland and Northern Ireland. It means they will no longer need to self-isolate for 10 days.

The green list - which has no quarantine for returning passengers - is being expanded. Countries listed now include:

Four countries will move from the red to the amber list: India, UAE, Qatar and Bahrain.

La Reunion and Mayotte, both French islands in the Indian Ocean, will be moved to the stricter red list, along with Mexico and Georgia.

The Welsh government is yet to confirm whether it will make the same changes.

Going on holiday abroad means taking Covid tests.

You may need one before setting off - each country has its own rules for arriving holidaymakers.

Then, in the three days before returning to the UK, you will need to take a PCR or lateral flow/antigen test. You will need to show a negative result before boarding and cannot use the free NHS tests.

Lateral flow/antigen tests can be bought in the UK to take with you, or you can buy these or PCR tests when you are away.

It is your responsibility to make sure they are of the right quality.

For passengers returning from Spain, the government now advises you to use a PCR test instead of choosing to use a lateral flow test.

For green and amber list countries a further PCR test is needed after arrival in the UK, which must be booked before you leave.

Most private providers charge above £60 for PCR tests and £30 for lateral flow devices. Some travel companies offer discounts.

Nobody has to self-isolate after visiting countries on the green list.

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.

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. This will apply to arrivals from France to England, Scotland and Northern Ireland from Sunday onwards.

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

Those arriving from Spain are being asked to use a PCR test for the first of those two tests.

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.

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 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:

From 8 August, 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.
