As the debate over Votes at 16 in the UK reheats - here are 5 voting age quirks from around the World.
Whilst in Indonesia, the legal voting age is 17 - if an individual is 17 years old and married, they can get a document called a Kartu Tanda commissioned - which allows them to vote regardless of whether they're over 17 or not.
In Croatia, as in the UK, the voting age is still 18. The quirk here being that if an individual is in gainful employment, rather than a student or on welfare, they can vote at the age of 16.
Despite literacy tests to determine voter eligibility being hugely controversial historically in the United States, Ecuadorians are split based on literacy when it comes to voting. It's compulsory for any literate person between the ages of 18-65 to vote, whereas it's only optional for any other eligible voter.
In many countries, members of the armed forces - sometimes even the police - are restricted from voting. In Guatemala, servicemen and women are actually confined to their barracks on election day to prevent them casting a ballot or influencing the vote in any way.
In Bolivia, voting is compulsory. This isn't particularly a quirk in itself, but the age fluctuates - if you're married, age is pretty much irrelevant, whereas for single people, the legal voting age jumps to 21.
