The success of the book in the US prompted Cornerstone publishers to buy the UK rights to the novel and its two sequels, Fifty Shades Darker and Fifty Shades Freed, which are released next week.

The trilogy of stories tells the tale of a steamy romance between "successful young entrepreneur", Christian Grey and "unworldly, innocent" literature student, Anastasia Steele.

The book has broken the weekly sales record for an erotic novel surpassing Anais Nin's Delta of Venus, which sold 510 copies in one week in 2004, according to Nielsen BookScan.
