Martin Lewis has warned a passport rule could see British holidaymakers sent home from airports.

The BBC Sounds podcast host appeared on ITV's This Morning.

Martin explained: "You also need to check that your passport is not over 10 years old on the date you enter. You used to be able when you renewed your passport to take what you had left on your old passport and add it to your new one so you got more than 10 years.

"But now many countries will not let you in if your passport is older than 10 years."

He went on to say: "This is not a small thing. People do their flight and then get sent back, they get sent back and you can't travel. I know someone it happened to in Dubai because of the 10-year rule."

UK travellers used to be able to carry up to nine months left on an old passport over to a new one. This meant that a passport could be valid for more than 10 years.

But the rules changed after Brexit, and most EU countries no longer accept British passports that were issued more than 10 years before the travel date.

This is known as the "10-year rule".

To enter those countries now, your UK passport must have been issued less than 10 years before the date you enter the EU country (the "date of issue") and be valid for at least three months after the day you plan to leave (the "date of expiry").

You will be refused entry if your passport does not meet these requirements. The rules apply in all 27 EU countries, except Ireland, the BBC has reported.
