MUMS and dads are being urged to keep a closer eye on what their children are up to on the internet.
The call came from Colne Valley Labour MP Kali Mountford, who says she was shocked by the findings of a national survey.
The YouGov survey said nearly two-thirds of parents allowed their children to use the internet at home unattended.
Ms Mountford said: "The findings are amazing, especially when the survey also showed that 94% of parents know paedophiles can have direct contact with children through chat-rooms or other internet services."
She called on parents to monitor their children's internet use in the same way as they would check on what they were watching on their televisons.
Ms Mountford added: "The vast majority of parents are aware of the potential dangers to children from the internet, so they ought to be vigilant, to make sure their youngsters are not viewing inappropriate images.
"If children are found to watching something they shouldn't, parents have the ultimate deterrent of switching off the computer."
The YouGov survey, commissioned by electrical retailer Comet and the NCH children's charity, revealed that only 17% of people questioned said their child never used the internet at home unattended.
