The campaign includes many SNP members, as well as members of many other parties, businesses, and communities. Among those on stage supporting the announcement were Scottish Green Party co-leader Patrick Harvie, actor Alan Cumming, former politician Dennis Canavan, poet Liz Lochead and actor Brian Cox.
