UK Prime minister David Cameron has said that the country’s Internet services providers will be asked to automatically block access to online pornography sites unless the subscribers opt to receive it.

Cameron said online pornography is corroding childhood and that must be stamped out.

Cameron said: "Children can’t go into the shops or the cinema and buy things meant for adults or have adult experiences – we rightly regulate to protect them."

"But when it comes to the Internet in the balance between freedom and responsibility, we have neglected our responsibility to our children," he said.

Cameron said the government is keen introduce a "Family Friendly Wi-Fi" symbol which retailers, hotels and transport companies can use to show their customers that their public Wi-Fi is filtered.

As per the plans, by the end of 2013, if anyone sets up a new broadband account the settings to install family friendly filters will be automatically selected.

Last month, Cameron urged Google and other search engines to work more harder to prevent child pornography saying that he is sickened by the proliferation of child pornography.

Cameron has also proposed plans to help parents protect their children online by adapting their computer settings to block internet pornography, violence and other unsuitable websites.
