Almost 1m copies of former US President Bill Clinton's memoirs have sold in under a week, his publisher has said.
The book had a record-breaking initial print run of 1.5m copies
The autobiography My Life hit the shelves in the US last Tuesday and had sold 935,000 copies by the end of Sunday, publisher Alfred A Knopf said.
It sold 400,000 copies on its first day, the biggest debut ever for a non-fiction book and double the record held by Hillary Clinton's Living History.
A spokesman for Knopf said the million mark should be reached very soon.
International sales figures are not yet available for the book, which had a record-breaking initial print run of 1.5m copies.
Despite a rather chilly reception by reviewers, it is already in its third print, with an expanded print run of about 2.6m copies.
The 937-page book follows Mr Clinton's life, from his earliest beginnings as a child growing up in Arkansas to the White House.
It gives frank details of his time in office, including his notorious affair with White House intern Monica Lewinsky.
