A LABOUR MP has condemned Edinburgh author and millionairess JK Rowling for allowing supermarkets to sell cut-price copies of her latest Harry Potter novel.
Lynne Jones has said such "extreme discounting" could put small bookshops out of business.
And the Birmingham Selly Oak MP wants authors and publishers to stop supermarkets undercutting other outlets by two-thirds.
Ms Jones's Early Day Motion reads: "I note that copies of Harry Potter And The Half Blood Prince are selling in supermarkets for as little as 4.99 compared with the trade price for lower volume outlets of 10.70 and the retail price of 16.99.
"I therefore call on publishers and best-selling authors like JK Rowling to consider the threat to the viability of bookshops of such practices offering a full range of titles and to set terms in publishing contracts to prevent this extreme discounting."
Meanwhile, ten MPs, led by East Dunbartonshire Liberal Democrat Jo Swinson, have put down another EDM defending Ms Rowling against criticism from the Pope that her books might encourage children to become interest in the occult.
It says: "We welcome the launch of Harry Potter And The Half Blood Prince and the excitement and enthusiasm for reading the series has sparked among children."
