Key figures in the formation of the FSN were Neil McCormick and Allan MacCartney who would both later become SNP members of the European Parliament.
The FSN is an autonomous body from the SNP and as such can devise it's own policies, publicity and campaigns. Unlike the SNP it is expressly republican, and has in the past exhibited socialist sentiment.
It has played an active part in the affairs of the SNP and is represented on the party's National Executive Committee and can send delegates to it's Annual National Conference and meetings of it's National Council.
The FSN supported the bid for SNP leadership of Alex Neil in 2000.
