Listen: In the span of just 48 hours in early September, the United Kingdom got a new prime minister, Liz Truss, and a new monarch, King Charles III. Both face big challenges in their new roles. For Truss, the Tory leader: a range of issues from inflation to the ongoing fallout of Brexit. For Charles: the relevance of the monarchy itself, now that Britain's longest-serving and much-beloved queen is gone. The United Kingdom also faces staggering inflation and a looming energy crunch. On the GZERO World Podcast, Ian Bremmer talks with a man who occupied 10 Downing Street for a decade - former prime minister Tony Blair - about the road ahead for his country. Blair believes there will be a lot of uncertainty over the next year or two if Truss insists on big tax cuts and big borrowing. He also looks back at the queen's legacy and the future of the monarchy, explains why Brexit will hurt - but probably not fragment - the UK, and argues that we need to return to his comfort zone of the political center to fix today's problems.
