Investigatory Powers (Amendment) Bill [Lords]

I sense that the Home Secretary is coming to the end of his speech. We have mentioned parliamentarians and journalists, but I want to talk about another important group: trade unions. Some people fear that the Bill will open the door even further than its parent Bill on the surveillance of trade unions. Does the Home Secretary agree that there should be no place for the surveillance of trade unions in a democracy? If so, will he consider amendments to the Bill to ensure that that does not happen, including a redraft of clause 5?
