It is really not surprising that we see an increase in support for the Union ("Independence blow as support for Union soars", The Herald, October 8 .

Angus Robertson, the SNP's defence spokesman, has been pushing the idea of his party abandoning its principled opposition to Nato. This may well cause a more substantial and damaging loss of support for independence.

Meanwhile Nicola Sturgeon is on record as affirming the SNP's "unqualified opposition to nuclear weapons".

This is excellent. It is also totally irreconcilable with membership of Nato, an organisation which supports the threatened use of the very nuclear weapons to which the SNP has "unqualified opposition".
