British security services warn attack in UK is ‘very likely’

A terrorist attack in the UK is "highly likely" following attacks in other parts of Europe, a five-judge tribunal has been told.

Britain's intelligence agencies highlighted the seriousness of the threat as they defended themselves against accusations of engaging in themass collection of communications data and UK citizens' personal information without proper legal safeguards being in place.

The charity Privacy International has taken the issue before the Investigatory Powers Tribunal (IPT) in London in a hearing expected to last four days.
