Nicola Sturgeon
With the SNP announcing its plans for an independent Scotland this week, Lesley Curwen profiles Nicola Sturgeon - a figure who may be key to the party's chances of success.
She's deputy to Alex Salmond but is central to the party's campaign, and she's playing a major but perhaps under-reported role in negotiating with London too.
How did she achieve such a rapid rise to political prominence? And why is she so obsessed with the TV drama Borgen?
Presenter: Lesley Curwen Producer: Chris Bowlby.
