Jennifer Tracey and Eddie Mair present iPM, the programme that starts with its listeners. This week: "Do the parties have policies directed at middle-aged, single, working voters who don't have children?" We explore the winners and losers when politicians focus on "hard working families". Jennifer Tracey returns to the home of a listener whose life is usually blighted by aeroplane noise but, thanks to the Volcano, has this week heard birds and bees. Also, does a history of mental health issues preclude you from standing as an MP? Carole Walker presents this week's Your News bulletin, and Martha Kearney makes a guest appearance in the podcast.
