A horrified mum revealed the latest TV phone-in scandal when she claimed that a girl was used as a fake caller in a competition on kids' favourite Blue Peter.

Mona Zahoor was visiting the Blue Peter studio when she reportedly witnessed the 12-year-old girl ring up after a technical fault meant 14,000 competition calls were ignored.

The Mirror reports that children were asked to call in to identify a star from a picture of their shoes, but a technical fault meant no callers could get through. So a member of the production team asked the girl to ring in from the studio. She pretended to be 'calling from London' - and won the prize.

CBBC controller Richard Deverell said: "The decision to put a child on air in this way was a serious error of judgment. I apologise to viewers and the children."
