There are calls to lower the voting age to 16 to involve young people in elections more, as the UK prepares to go to the polls.
Campaigners say 16-year-olds should be allowed to vote as they have strong ideas about how to run the country.
As 16-year-olds can leave home, get a full-time job and raise children, they should be allowed to vote, they say.
This comes as we are one day away from a General Election, where the people will decide who the next government is.
Millions of people aged 18 and over will cast their vote in polling stations on Thursday. Surveys on Wednesday show the Labour Party - the most recent governing party - has a lead over the Conservatives, with the Liberal Democrats in third place.
In 2004, there was a big review into whether the voting age should be lowered to 16, and the group looking into it decided not to.
Groups campaigning for this change include the National Union of Students, the Electoral Reform Society, the Children's Rights Alliance for England, British Youth Council and Children's Parliament in Scotland.
