Snapchat 'Files for Stock Market Float'

Available for over a year

The social media app Snapchat could be worth as much as $25 billion. We ask Rhiannon Williams, technology correspondent of the i newspaper what's behind its popularity. Also in the programme, we look at the business case for a massive expansion of the BBC World Service, announced today, with Solomon Mugera, the BBC's regional editor for Africa. Some of the biggest names in American business are urging Donald Trump to stick to the US's commitments on climate change. We hear more from Barry Parkin, global sustainability director for the Mars confectionery company, and we have analysis from Andrew Simms of the New Weather Institute. Plus the BBC's James Copnall reports from Ivory Coast on efforts there to rebuild the country's tourism economy following an attack that killed 19 people earlier this year.
