Robotics, Trump and Brexit turn up the heat amid the snow of Davos

The world is full of scary new problems for delegates at this year's World Economic Forum - not that old ones like climate and poverty have gone away

Donald Trump's US election victory and the UK's vote to leave the European Union will cast a long shadow over the global elite's annual gathering in the Swiss ski resort of Davos this week.

This year, 3,000 politicians, business leaders, economists, entrepreneurs, charity leaders and celebrities will head to the World Economic Forum (WEF) to discuss the state of the world. As usual there'll be big speeches, ultra-tight security, and experts in every field under the wintry sun. There'll also be plenty of champagne and canapes for delegates gathering in expensive hotels to discuss issues such as inequality and the backlash against globalisation.
