In Turkey, an old social media post can be a criminal offence
What happened
On 18 September 2026, the Foreign, Commonwealth and Development Office updated its travel advice for Turkey. The change was to the safety and security section, and it is about what people say - including what they said online, a long time ago, from home. The advice now states: "It is illegal to insult the Turkish nation or the national flag. Insulting the President or the founder of the Turkish Republic, Mustafa Kemal Atatürk is also a criminal offence." Then comes the part that catches people out: "These laws can apply to comments or images online no matter where you were or when you posted them." The penalty range set out in the advice is six months to three years in prison. The advice also notes that defacing banknotes is covered by these laws, because Turkish banknotes carry a portrait of Atatürk.
Why this matters
Turkey is one of the most popular holiday destinations for British travellers. Most trips pass without any trouble at all, and nothing here changes that. What has changed is the FCDO's emphasis on something many people simply do not think about. We are used to the idea that the law of a country applies while you are in it. What is less familiar is the idea that a post made in Britain, years ago, in a moment of irritation about a news story, can be treated as an offence when you land. Phones are routinely checked at some borders, and social media accounts are public by default. A joke, a shared image or a heated reply in a comment thread does not feel like a legal act at the time. This is not unique to Turkey. Several countries have laws about insulting the head of state, the flag or the nation. Turkey's are simply set out clearly in the advice, which is helpful rather than alarming.
What the evidence actually says
This is official UK government advice, published on GOV.UK. It is not a rumour or a news report, and it is the most reliable source there is on this question. A few things are worth reading carefully. The advice describes the law. It does not say how often it is enforced against tourists, and no figures are given. Most visitors will never come close to this. The phrase "no matter where you were or when you posted them" is the important one. It means the protection people assume they have - it was years ago, I was at home, it was only a joke - is not the protection they think. The six months to three years figure is the penalty range set out in the advice, not an average sentence. And there is a practical point worth naming. If you are detained abroad, the British consulate can help in specific ways - contacting your family, giving you a list of local lawyers, visiting you. It cannot get you out of prison, pay your legal costs or interfere in another country's legal process. That is the same everywhere, and it is why prevention matters more than cure.
Practical advice
None of this requires anxiety. It requires about ten minutes before you travel. Read the FCDO advice for Turkey, or for wherever you are going, and read the safety and security section rather than just the top line. Advice can change while your holiday is already booked. Sign up for email alerts on the GOV.UK travel advice page for your destination. It is free and it tells you when anything changes. Have a quick look at your own social media. If you have posted something about Turkish politics, the flag, the president or Atatürk, consider whether you want it public while you are there. This applies to shared posts and comments, not just your own words. Be careful with Turkish banknotes. Do not write on them, tear them or deface them, even as a joke. Be careful in conversation too. Political discussions with strangers, and photographs at demonstrations, are worth avoiding. Make sure you have travel insurance, and check it covers legal expenses. Many policies include some cover, and it is the kind of thing nobody reads until they need it. If you are detained, ask to contact the British Embassy or Consulate immediately. The FCDO can be reached from abroad on +44 20 7008 5000, 24 hours a day.
What to know
The FCDO updated its Turkey travel advice on 18 September 2026 to warn that insulting the Turkish nation, the national flag, the President or Mustafa Kemal Atatürk is a criminal offence, carrying six months to three years in prison - and that these laws can apply to online comments or images regardless of where or when they were posted. Defacing banknotes is covered too. Millions of people visit Turkey without incident every year, and this is not a warning against going. It is a reminder that the rules about speech are different in different places, and that the internet does not respect borders. The ten minutes it takes to read the advice and glance over your own posts is the whole of the precaution.
