A new travel permit will soon be needed for entering certain European countries such as Spain, France, Italy and Turkey.
Set to come into force in 2024, the European Travel Information and Authorisation System (ETIAS) is a travel permit that will cost around €7 for those over the age of 18.
At the moment, people from the UK don't need a visa to enter countries in the Schengen area - which is most of Europe. But now, holidaymakers have been warned that they could be barred from travelling if they don't have an ETIAS in place.
