Snowden backs web 'magna carta' bid in surprise appearance

NSA whistleblower Edward Snowden has made a surprise appearance as a speaker at the TED conference in Vancouver, claiming certain governments wanted him dead.

Mr Snowden appeared on-stage on a remote screen alongside Sir Tim Berners-Lee, credited with the invention of the World Wide Web, who was putting forward his vision of a magna carta for the Internet that would enshrine the right to web freedom.
