       A book by Meghan Markle would easily make its way onto the "bestseller" list, according to a royal author.

       The 41-year-old has kept her lips sealed since the sensational publication of Prince Harry's memoir in January leading many royal experts to claim she is working on her own book.

       Royal author Christopher Andersen believes the Duchess of Sussex will "take advantage" of her current standing after the royal couple have received months of criticism.

       He told Us Weekly: "We've seen her perspective with some examples but I'm sure there's always another rabbit to pull out of the hat, some fact that we didn't know to put into a book.

       "I'm sure if she wanted to write a book, it would be an enormous bestseller because once again it would contain things we don't know yet.

       "I would imagine that is probably not in the distant future, I think they're going to take advantage of where they are and she will do something like that."
