E.L James' FIFTY SHADES OF GREY becomes the bestselling British book of all time! The trilogy has sold over 12 million copies nationwide.
— Random House Group (@RandomHouseUK) August 7, 2012
Note - The book was first commercially published on 20th June 2011
Note - Some confusion here! Random House say it's the best selling book, but then give sales figures for the trilogy? Random indeed.
They've since deleted the tweet, but this one still exists:
Many congratulations to
@e_l_james FSOG is now the bestselling book of all time in the UK @fiftyshadesuk @arrowpublishing
