Potter to give away only interview to young fan

The UK's biggest Harry Potter fan will get the chance to interview author JK Rowling.

The world's press are clamouring to quiz Rowling about the release of her forthcoming book Harry Potter and the Half-Blood Prince, but the writer is giving her only UK TV interview to one of her young fans.

The lucky winner will be among 70 children from around the world invited to Edinburgh Castle to meet the author and attend a kids-only press conference.

The nationwide search is now on for the fan who knows the most about the schoolboy wizard.
