A-list actress Emma Watson has been leaving copies of books on the London Underground as she continues to champion equal rights through her new book club.

First acting, then modelling, followed by championing feminism, the former Harry Potter star is no stranger when it comes to speaking up for causes she believes in.

And now the launch of her new book club, Our Shared Self, has led the 26-year-old, famous for playing Hermione in the movie adaptations of the J K Rowling novels, to hide copies of Maya Angelou's 'Mom & Me & Mom' at different stations around London this week.

The A-lister took it upon herself to spread the word about books on the tube

Sneaking around the capital's transport network as part of the Books on the Underground campaign, she left the late author's text for Londoners to enjoy.

Books on the Underground director, Cordelia Oxley, said: "The campaign with Emma Watson is perfect as it promotes her feminist book club Our Shared Shelf, and also reminds people to look around for a hidden book when they're on the tube."

Watson, who is also the UN Women Global Goodwill Ambassador, was delighted to be the "book fairy", according to her Facebook post about the endeavours.

Watson, who is soon to be appearing in a live action adaption of Beauty and the Beast as Belle, wrote: "I've been hiding copies of Mom & Me & Mom for Books on the Underground on the tube all day, see if you can find one tomorrow."
