UK travellers to countries across Europe are being warned that their passports may not be valid even if they have 15 months validity left.
People may also need to get an International Driving Permit to drive in EU and European Economic Area countries if the UK leaves the EU without a deal.
The scenarios were spelt out in updated travel advice from the Foreign and Commonwealth Office if there is a no-deal Brexit.
“If the UK leaves the European Union with no deal, the passport validity rules for travel to most countries in Europe will change from 29 March 2019,” the FCO said.
“Some passports with up to 15 months validity remaining may not be valid for travel.
“Before booking travel, you should check that your passport will meet meet these new rules and find out whether you need to renew it.”
The FCO pointed out that there are three types of International Driving Permits.
“Check that you have the correct permits covering all countries where you will be driving – you may need more than one IDP,” it added.
