It has been a year like no other for two of Britain's best-known institutions. The BBC, the country's independent public broadcaster, has found its editorial integrity in question, and has been forced to defend its practices on multiple occasions. The British monarchy too, is under greater scrutiny than perhaps ever before. David Dimbleby is a veteran journalist who knows both institutions well. "What's the Monarchy For?" is his latest project airing on the BBC now. He joins the show from London. 

Also on today's show: author Kiran Desai ("The Loneliness of Sonia and Sunny"); Minnesota State Senator Zaynab Mohamed
