Deputy First Minister Nicola Sturgeon is to argue the case for independence within the context of ending child poverty, as she addresses campaigners.
Ms Sturgeon is giving the keynote speech at an event in Edinburgh's National Museum of Scotland, organised by the End Child Poverty campaign.
The event is the first in a series which will debate what the different constitutional options mean for reducing child poverty in Scotland.
John Dickie, speaking on behalf of Scottish members of the campaign, said: "At the heart of the constitutional debate must be the basic question about what kind of society we want to live in. Is it a Scotland where child poverty is challenged and action is taken to end it? Or is it a society that continues to be marked by the shame of child poverty, one that undermines one in five childhoods and prevents children from reaching their full potential?
"The debate about our constitutional future reminds us that there are real choices to be made about the future of our country and about the priority we give to measures to address child poverty."
