Have you got a son or a daughter (I could have simply put 'child' couldn't I?) who really digs the magical world of Harry Potter and crew? I've haven't read the books or seen the films so I don't understand the fuss, but that shouldn't mean a damned thing to you. What am I talking about? Oh yes. If you have a child that likes Harry Potter, you'll be thrilled to know that to celebrate the publication of Harry Potter And The Deathly Hallows, Blue Peter has launched a nationwide competition for 25 children to win a trip to see the Blue Peter Studios and guest, JK Rowling.

To enter the competition, children need to write down a question they would like to ask JK Rowling. On the opposite side of their A4 piece of paper, they then need to draw a portrait of themselves, as a witch or a wizard. For more details, visit the Children's BBC website (by clicking here) and click on Blue Peter, but get a wriggle on because the closing date is Friday 15 June.

Editor, Richard Marson, says: "We have always been great supporter of JK Rowling, so we are delighted she has decided to appear on our Blue Peter special, which will be shown on 20 July."
