Online surveillance bill 'will fall without judicial oversight'

Former shadow home secretary David Davis says investigatory powers bill will have to let judges' authorise warrants

Plans to grant police and intelligence officers new powers to monitor suspects online will not get through parliament without a requirement for judges to sign off on spying warrants, the former Conservative shadow home secretary David Davis has said.

The backbench MP was speaking before the publication of a draft of the investigatory powers bill, due on Wednesday, with the Home Office so far refusing to indicate whether the proposed legislation will include judicial approval of applications made by the security services to intercept communications.
