William Hague: UK agencies uphold the law at all times

Allegations that the data-gathering centre GCHQ circumvented the law to gain information on UK citizens are "baseless", William Hague has said.

Ex-CIA worker Edward Snowden claims US agencies gathered and shared phone records and internet data with allies.

GCHQ is to hand a report to MPs on Tuesday. Gordon Corera reports.
