Cameron: 'Robust powers needed to keep people safe'

David Cameron says he will revive plans for a communications data bill - branded a "snooper's charter" by critics - if the Conservatives secure an overall majority in May's general election.

The Liberal Democrats have made it clear that they see the bill, which would allow the security services to monitor the content of people's internet usage, as an erosion of the fundamental liberties that the government should be protecting.

Speaking in Nottingham, Mr Cameron said the Paris attacks demonstrated the need for "robust powers" to "keep our people safe".
