What legal age do you have to be to become a MP?

Answer 1

If you are talking about an MP in terms of a Member of Parliament, rather than a Military Policeman, then it would be when an election is called. Countries have general elections, when all MPs must stand for re-election, but there are also by-elections resulting from an individual MP resigning or dying, leading to a need for a replacement. Depending on the country, there is different criteria required to stand for election, so those would be factors too.

You would also need to have some experience, perhaps having been elected in a local council, or having considerable community work experience and probably education in other relevant areas. Many elected officials have legal or financial or other such qualifications before going for election. This helps them in their work as an elected official, and also gives them something to return to when they are finished with politics.

Answer 2

You have to be over 21 to be an MP.
