The UK does not have an official language.
However, the most common languages spoken in the UK, based on 2021 census data, are:
1. English: Spoken by the vast majority of the population.
2. Polish: The second most common language spoken after English.
3. Urdu: The third most common language spoken in the UK.
4. Gujarati: The fourth most common language spoken in the UK.
5. Bengali: The fifth most common language spoken in the UK.
It's worth noting that these numbers represent the most common home languages, meaning the language a person speaks at home, not necessarily their primary language. The UK is a very multicultural society, with people speaking a wide variety of languages from around the world.
