After much hype and anticipation, first-night sales of the latest and final Harry Potter book were the highest on the series. In the UK the book is reported to have sold at least three million copies in 24 hours, while in the US it has sold 8.3 million copies in its first 24 hours, according to publisher Scholastic.
The Telegraph reports that supermarket chain Asda, which is selling the book for £5, said it had already sold 97 per cent of its initial 500,000 copies of Harry Potter And The Deathly Hallows and was hoping to take delivery of more this week.
"We've sold 100,000 copies in the first two hours across the business in the UK," said Fiona Allen of Waterstone's. "That has outstripped anything we've sold before."
The book sales and the success of the film series, which has just been continued with the release of Harry Potter and the Order of the Phoenix will be a major boost to master-toy licensee Corgi.
