Only on the "CBS This Morning" podcast, Financial Times U.S. editor-at-large Gillian Tett joins CBS News' Errol Barnett to discuss the United Kingdom's impending departure from the European Union. Tett, who is also the chair of the editorial board, explains why the exit will take place at 11 p.m. on Friday, instead of midnight. She also discusses the uncertainty surrounding how the split will play out on the world stage, in terms of travel, trade and immigration. Tett describes the Brexit-fatigue many people are feeling and the longing to return what she refers to as Britain's "boring" politics.
