British Tory MP Hugo Swire says that the Internet should be a "two-tiered" system, with a default children's setting that eliminate users' ability to access some sites, such as internet gambling or pornographic sites.

Users would have to use a pin or a password to access unfiltered material.

Mr Swire called for a UK regulatory body for websites, which he dubbed the "internet standards authority", which would create the database of blacklisted sites and update this hourly.

This could work "along the lines of the Advertising Standards Authority or the Press Complaints Commission", and would be responsible for policing "harmful content" online.

Among the sites coming into this category would be "glorification of violence and terrorism, pornography, cyber-bullying, suicide, internet gambling and anorexia websites", Mr Swire added.
