Which of the following countries does not have a written constitution?

The UK is a classic example of a country that does not have a single, codified written constitution. Its constitution is uncodified, meaning it is derived from various sources including statutes, common law, conventions, and treaties, rather than being contained in one supreme document.

• India has a comprehensive written constitution, adopted in 1950, which is the longest in the world.
• The US has a foundational written constitution, ratified in 1788, serving as the supreme law of the land.
• New Zealand also has an uncodified constitution, similar to the UK, but the UK is the most commonly cited example for this question.
