Jacqui Smith in radio porn show

Former home secretary Jacqui Smith, who claimed on parliamentary expenses for two adult films watched by her husband, is making a documentary about the porn industry.

The politician, who lost her seat in the 2010 election, will interview porn stars and film-makers for the Radio 5 show Porn Again.

She said: "As I know from my personal experience, porn fascinates us - media and public alike. But we actually know very little about what it's like to work in the industry and what porn is doing to our society."

Ms Smith quit as home secretary in 2009 after a newspaper revealed two adult films had been charged to the taxpayer.
