Andrew Morton is perhaps the most famous royal biographer of all time, with his book Diana: In Her Own Words changing the way the world looked at The Firm forever. This week he sits down with Zoe Forsey to talk about his latest book, The Queen, which celebrates the Monarch’s 70 years on the throne. He also shares his thoughts on the latest royal dramas, including what he believes Diana would have thought of Princes William and Harry’s fallout and the mistake the Duchess of Cambridge made when the Queen expressed her wish for Camilla to become Queen Consort.
