Guardian plans to publish more of Snowden's 'snoop-op' data despite MI5 warnings

Guardian editor Alan Rusbridger has reportedly decided to publish more from the trove of classified data revealed by whistleblower Edward Snowden, despite warning from UK's Military Intelligence5 (MI5) that publishing the information could risk the nation's security.

Rusbridger argued in favour of publishing the data and said that it helped to prompt a necessary and overdue debate after MI5 head Andrew Parker criticized the efforts by saying that making such information public gave terrorists the advantage.

According to the BBC, Snowden, who is currently in Russia after being granted political asylum, is known to have secret data about the US surveillance programmes, including some 58,000 files from Britain's spy agency GCHQ alone.

Parker warned that terrorists now had tens of thousands of means of communication through e-mail, IP telephony, in-game communication, social networking, chat rooms, anonymising services and a myriad of mobile apps and revealing information about the government way of tracking such networks was threatening to the country.

Meanwhile, an independent MP Patrick Mercer said that intelligence data should not be published if it compromised public security, the report added.
