Is it a requirement to be at least 21 years old to become an MP?

To understand the age requirement for becoming a Member of Parliament, it's helpful to consider the broader context of political participation in the UK. While the voting age is 18, the requirements for standing for election are slightly different. The minimum age to stand for election as an MP is also 18. This reflects the idea that young people, once they reach adulthood, should have the opportunity to represent their constituents in Parliament. There isn't a higher age threshold. Some people might incorrectly assume that the age would be higher, perhaps 21, thinking it reflects a level of maturity or experience deemed necessary for such a role. However, the UK legal system allows anyone over 18 to stand for election, trusting the electorate to decide whether a candidate is suitable, regardless of their age beyond that minimum.
