Stealthy operators

WEEKEND reports of the russian intelligence services being involved in the pro-yes campaign to break up the UK in 2014 should not be dismissed lightly.

any weakening of UK defence and Nato capability would be worthwhile for the russians and that is exactly what would have ensued had those pushing for separation won.

We should not forget, either, that in the past Western intelligence has worked to destabilise potential enemies in much the same way, so it is nothing new. ALEXANDER McKAY, Edinburgh.
