Michelle Obama has best-selling memoir

Michelle Obama's memoir Becoming looks set to become the biggest-selling autobiography ever after it sold 10 million copies globally in just five months, according to its publisher.

"We believe this could be the most successful memoir in history," Thomas Rabe, the CEO of Bertelsmann SE, the parent company of book publisher Penguin Random House, told reporters in Berlin, where Bertelsmann is based.

The publisher paid $60 million to Michelle and her husband, Barack Obama, the former president of the United States, for rights to a book written by each of them after they left the White House in 2017.
