Official launch of Yes Campaign in Wales
The group aiming to persuade voters in Wales to back more powers for the assembly in March's referendum is to officially launch its campaign.
Yes For Wales is backed by all four major political parties and chaired by Welsh Rugby Union Chief Executive Roger Lewis.
Mr Lewis will lead the launch in Cardiff on Tuesday, to be followed by a series of regional events on Wednesday.
The No campaign against further powers is being led by True Wales.
Mr Lewis said: "People from across our country are coming together to unite behind a simple principle.
"We believe laws that only apply in Wales, should be made in Wales. That's what this campaign is all about."
The launch is taking place at the University of Glamorgan's Creative and Cultural studies centre, the Atrium at 0930 BST.
The referendum takes place on 3 March.
