Parents have flooded a British primary school with complaints after a teacher told a room of tearful seven-year-olds that "it's your parents who leave out presents on Christmas Day," The Daily Mail reported.

Outraged parents were sent a letter saying the substitute teacher at Blackshaw Lane Primary School in Royton, Greater Manchester, had been disciplined.

The class of 25 allegedly became rowdy talking about Santa Claus and the teacher blurted out that he did not exist in an effort to calm them down, The Mail reported.

"My son came home and said that his substitute teacher had told the class that Santa doesn't exist," one father told The Mail. "I thought it was wrong. He was distraught about it. He's only seven-years-old and it's part of the magic of Christmas to him."
