During the Q&A section of the presentation Nicola Sturgeon was asked: “You say a win in this election reinforces the case for an independence referendum. If you lose seats will it weaken your case on independence?”
The question was initially met with boos from the party faithful attending but the 46-year-old, who is hoping to be re-elected at the country’s First Minister dodged the probing question to lecture on the fundamentals of the democratic process.
She said: “Can I say directly to that, maybe I’m old fashioned but the person who gets more, or the party rather, that gets more votes and more seats wins the election. It’s democracy.”
