A bill to lower the voting age to 16 in the independence referendum has been formally lodged in the Scottish Parliament.
The idea was agreed in principal last year by First Minister Alex Salmond and Prime Minister David Cameron.
If passed, it will be the first time in the UK that the franchise has been extended to include 16 and 17-year-olds in a national poll.
A separate Bill detailing the proposed single question referendum will be brought forward later this month.
