Head judge, children's author Sam Hay, selected her overall winner as nine year old Anouk Wood, from Leighton Buzzard, for her story Urgent! Make Santa A New Suit.
In the 4-6 age category, Oliver Green, 5, from Preston won for his story The Magic Of Christmas, while in the 10-11 age category, it was Jay Evans, 10, from Bristol, who took top prize thanks to his story If Christmas Was A School Day.
Sam says: "Christmas inspires so many stories and clearly sparked the imagination of the children who entered. It was a joy to read all of the entries. Anouk's story had amazing originality and made me laugh. Who knew the secret to making a magic Santa suit was a dollop of ketchup and some raspberry jelly. I hope everyone has a very merry Christmas and writes more fabulous stories in 2016."
