Lawmakers Blast Facebook

A Canadian MP accuses 'Frat-boy billionaires from California' of upending democracy. Plus, we hear the story of Sophie Roberts, an Amazon software developer who came out as transgender to her colleagues. And Emma Lawton from the charity Parkinson's UK tells us about a suite of apps aiming to help people with the disease manage their symptoms. Presented by Rory Cellan-Jones, with BBC tech reporter Chris Fox and special guest Mark Scott, chief technology correspondent at the Politico website.
