Wikipedia founder Jimmy Wales on the internet's future

Wikipedia founder Jimmy Wales has warned that "we can easily wreck the internet", if the wrong kind of government legislation is put in place to guide its development.

In a wide-ranging interview with the BBC's Rory Cellan-Jones at the Cyberspace conference in London, he discussed the global outlook for the internet, and the position of Wikipedia in China.

Mr Wales is in London to deliver the Free Thinking Lecture at the BBC Radio 3 Free Thinking Festival 2011.
