Harry Potter has lost out to the Wimpy Kid in a poll to find the best children's book of the past 10 years.

Diary Of A Wimpy Kid, US author Jeff Kinney's comic tale of the trials faced by hapless Greg in his school life, was voted to the top spot by children.

Published as an illustrated diary, it started life online but has since spawned six books and a film adaptation.

Voters in the Blue Peter survey were asked to select their favourite title from a short list of the 10 bestselling children's fiction books for five to 11-year-olds in the past 10 years. Only the top seller for each author was included.

As well as JK Rowling's Harry Potter And The Order Of The Phoenix, the list featured bestsellers by former Children's Laureate Jacqueline Wilson and Michael Morpurgo.

Mr Kinney said he was "thrilled" to receive the accolade. He added: "I'm so grateful to all of the Wimpy Kid fans in the UK who have supported my books right from the beginning."
