What countries use referendum?

Answer 1

Many countries utilize referendums as a means of direct democracy, allowing citizens to vote on specific issues or policies. Notable examples include Switzerland, where referendums are a common practice at both the national and cantonal levels, and Italy, which frequently holds referendums on constitutional and legislative matters. Other countries, such as France and Australia, also employ referendums, though less frequently. Additionally, some nations, like the United Kingdom, have used referendums for significant decisions, such as Brexit.
