The web should remain neutral and resist attempts to fragment it into different services, web inventor Sir Tim Berners-Lee has said.

Recent attempts in the US to try to charge for different levels of online access web were not "part of the internet model," he said in Edinburgh.

He warned that if the US decided to go ahead with a two-tier internet, the network would enter "a dark period".
