Scottish referendum 10 years on, with Better Together chief Blair McDougall

We look back at the pro-independence campaign in a two-part special featuring the leading figures from both sides. In this interview, we hear from Blair McDougall, the chief strategist of pro-UK group Better Together. He recalls working with the late Alistair Darling, political rivals, and considers if they took the right approach for a more definitive result.  Look out for our second interview, published at the same time, with Yes Scotland chief Blair Jenkins.
