Scottish teens grill pro-union MP Danny Alexander

It's exactly 100 days until decision day on Scotland's future. The referendum on independence takes place on 18 September.

A reminder of the question for you if you missed it: Should Scotland be an independent country?

Ellie Kean, Scott Faulds and Ellena Leslie from BBC Scotland's Generation 2014 project will be among the youngest voters.

They visited Westminster to interview Lib Dem MP Danny Alexander, who wants Scotland to stay as part of the UK.
