IT will surprise few that the SNP has, after months of pressure from supporters of independence, launched a Plan B in its quest to manage and keep control of how to effectively achieve independence. As pro-independence columnists have pointed out, the party’s track record in government is decidedly average, yet this is unlikely to affect the outcome of the elections in May (Kevin McKenna, "A Plan B for independence… so why has it taken six years?", The Herald, January 25). No, the real threat to the SNP in controlling the momentum of the independence debate comes from within the ranks of that movement, but outwith the party itself.
