MI5 chief calls for more up-to-date surveillance powers

Andrew Parker also says telecoms firms should provide more help in monitoring suspected terrorists and paedophiles

The head of MI5, Andrew Parker, has called for more up-to-date surveillance powers and said tech companies had an ethical responsibility to provide more help in monitoring the communications of suspected terrorists and paedophiles.

In the first live media interview ever given by a senior British intelligence official, Parker defended the British surveillance system and backed the government's plans for new surveillance powers.
