Obama says drift towards extremism 'not inevitable'

Barack Obama has told an audience in Glasgow that hope is worth fighting for despite big challenges facing the modern world. The 44th president of the United States said online platforms had shifted in recent years to focus on content that stoked anger and fear, but he believes a drift to extremism is "not inevitable". The comments came as he addressed an OVO Hydro crowd of 12,150 people while in conversation with British journalist and author Sathnam Sanghera, part of three speaking dates in the UK. He reflected on his time in the White House and examined the political and social challenges facing the US and the wider world.
