Investigatory Powers Bill

Will my right hon. Friend join me in paying tribute to Unite, the Union of Construction, Allied Trades and Technicians and the GMB, which fought a long campaign to raise the scandal of the illegal blacklisting and secret vetting of construction workers? Can he assure the House that such a gross injustice could not be perpetrated against innocent workers again, and that his amendment would provide an absolute guarantee that legitimate trade union activities would be excluded from monitoring by the security services and the police?
