How do the SNP sell a second referendum?

Could a second referendum on Scottish independence yield a different result? In September 2014 when Scotland voted against becoming an independent country it seemed like the question had been settled for the foreseeable future. All that changed on June 23rd 2016 when the UK voted to leave the EU. Just a few hours later - before she'd even been to bed - Scotland's First Minister Nicola Sturgeon was already talking about the prospect of another vote on independence. Ever since she has been ramping up the rhetoric. But what would the SNP's strategy be second time around?

BBC Scotland Editor Sarah Smith explores whether the SNP would dare call another vote when there seems little appetite and opinion polls have failed to move as much as Nicola Sturgeon might have expected following the Brexit vote. Sarah talks to strategists and politicians for an insight into how things might be different should a second referendum take place in the near future. She asks whether an independent Scotland would be accepted into the EU and what the future might hold for the first minister should she fail to achieve what she sees as her duty - offering Scotland another chance to gain independence.
