If we made a list of the people least likely to make a documentary about porn this year, former Labour Home Secretary Jacqui Smith would be at the top. The scandal that ended her 12-year political career in the summer of 2009 centred around two adult pay-per-view films that she’d claimed as part of her expenses; paperwork her husband Richard Timney put together in his role as her office manager. Weeks of press scrutiny, photographers on her doorstep and speculation about her marriage ended in a humiliating resignation. It was the kind of experience public figures rarely recover from. So why, almost two years on, has Smith made a documentary exploring porn, a move guaranteed to reignite the scrutiny? Is she a glutton for punishment, a limelight-seeking ex-politician or simply a woman with a mission?
