The UK boss of Viagogo, travel companies paying for positive reviews, tackling diabetes

Available for over a year

We reveal the travel companies paying for positive reviews online. As a court case could force the secondary ticketing website Viagogo to reveal where it gets some of its tickets Peter White speaks to its UK director Ed Parkinson. Our series on diabetes continues examining how much responsibility the public, the government and businesses will have to take in the future. We examine a new scheme that attempts to provide a more accurate measure of how many Miles Per Gallon (MPG) new cars can achieve. Plus we get a early look at the new Dreamliner - the Boeing made plane which is coming to the UK later this year. And Peter takes a 'sniffy city walk" - part of a project run by Manchester University to get us all to consider how smell effects our experience of place. Email [email protected] Producer: Joe Kent.
