Investigatory Powers (Amendment)Bill [Lords]

I accept what the Minister has just said, but where is the threshold for publicity? As he said, the Panama papers were widely distributed in the public domain, but somebody’s Facebook feed might be put into the public domain. If it gets into the national newspapers and on the internet, or it is shared by a certain number of people, do we then determine that it is in the public domain? We need to be very careful about this.
