Window on Westminster 29th January

This week on Window on Westminster with Brian Shallcross, we discuss the gender pay gap that still exists in the workplace, and we examine the very real possibility of refining used cooking oil as a biofuel for both power stations and diesel vehicles. Also this week, we meet the MP who is calling for new ways of controlling our street lighting. And as the massive digital switchover of our television systems gets ever closer, we talk to the Liberal Democrat Culture spokesman about how its going.
