Organisers say Generation Yes will be the "largest youth movement that Scotland has ever seen".
School pupils, students and young people from across the country gathered in Glasgow city centre yesterday. With 16 and 17-year-olds able to vote in the September 18 referendum, they targeted young shoppers as they handed out leaflets in Buchanan Street.
Toni Giugliano, sectoral groups adviser at the Yes Scotland group, said: 'We're launching the most dynamic and vibrant group of our campaign."
Glasgow schoolgirl Saffron Dickson, 16, said: "It's our chance to be the generation that takes our future into our own hands and stands up to inequality and unfairness in our society."
