David Anderson QC's report means Theresa May can move ahead with her controversial data legislation, but she faces potential opposition in the Lords
Powers that allow spy agencies to harvest bulk data were today given the go-ahead by the UK's terror-law watchdog. In David Anderson QC's report, published this morning, he said there was a "proven operational case" for most of the controversial methods of data collection.
Prime Minister Theresa May welcomed the findings claiming it showed how the powers, which she is currently trying to cement in legislation, are of "crucial importance" to MI5, MI6 and GCHQ.
But critics raised concerns over whether the Government would follow all of the report's recommendations, and raised the prospect of blocking them in the House of Lords if they are not happy.
Mr Anderson was asked earlier this year to evaluate the case for the tactics, which are included in the landmark Investigatory Powers Bill.
