Proposed powers for police and security services to access email and social media records would help prevent terrorists causing mayhem and murder on Britain’s streets, Defence Secretary Philip Hammond said today.

Mr Hammond added his voice to Home Secretary Theresa May’s drive to resurrect the Communications Data Bill in the wake of the killing of Drummer Lee Rigby in Woolwich last week.

His comments came after Conservative former police minister Nick Herbert branded Deputy Prime Minister Nick Clegg “irresponsible” for vetoing the Bill’s inclusion earlier this month in the Queen’s Speech setting out the Government’s legislative agenda for the coming year.

The controversial legislation would require internet companies to retain records of emails and social media messages for a year and allow police and security agencies to access the data, but not the content of messages. Critics have branded it a “snooper’s charter” and argue it would infringe privacy and act as a recruiting sergeant for terror groups.

But Mr Hammond argued that it would help preserve civil liberties by protecting citizens and troops from the threat posed by violent extremists.

The Defence Secretary told LBC 97.3 radio’s Nick Ferrari show: “Once a suspect is detained, the urgent need is to discover who else is in his network and who else might be about to commit a similar act.

“The danger that we’ve got, as technology develops, more and more communications are carried out over the internet, Voice Over Internet Protocols, Skype and so on, that the police and security services lose that ability to track that traffic.

“Of course, we have to do this in a way that is sensitive to the concerns about preserving civil liberties. But we preserve our civil liberties by making sure that those who want to murder our citizens and soldiers on our streets can be tracked and monitored and dealt with so that can’t cause that kind of mayhem.”

Mrs May made clear at the weekend that she wants to revive the legislation, telling the BBC: “I’m clear the law enforcement agencies, the intelligence agencies need access to communications data and that is essential to them doing their job.”

Her call was backed by Labour’s former home secretary Lord Reid and ex-security minister Lord West, as well as Liberal Democrat peer and former reviewer of anti-terror legislation Lord Carlile.
