Jim O'Neill asks if new challenges mean an end to the era of globalisation. As chairman of Goldman Sachs Asset Management, Lord O'Neill was seen as one of the high priests of globalisation - coining the term BRICs to describe the economic rise of Brazil, Russia, India and China. Now, many see the UK's vote to leave the EU, alongside the election of Donald Trump as indications that the world is turning away from globalisation. A stalling in the increase in global trade is seen as another significant indicator. Lord O'Neill believes that globalisation can be a positive force, lifting hundreds of millions of people out of poverty. But can this economic engine take care of those left behind by rapid, wrenching change? Producer: Helen Grady.
