It has been dubbed the year of rebellion - a year when everything that was assumed to be the political and social norm was turned upside down. After Brexit and the shockwaves following the American election, it would be no exaggeration to describe 2016 as the year that changed the world. In this special programme, Tom Bradby explores the Brexit vote in Britain and how it revealed a deeply divided nation, uncertain of how best to proceed under the highly pressured umbrella of the European Union. In America, the election of Donald Trump signalled a rejection of the elite and for many the start of a 'golden new age' for the US. Tonight takes a look at what has happened over the last 12 months and whether the rebellions that occurred will set the tone for years to come in other countries across the globe.
