I got a tailored response from my (Labour) MP at the time of the snoopers' charter passing. He largely agreed with the substantive points I put forward against the surveillance regime, but felt unable to vote against because (IIRC) the government had structured the legislation in such a way that if it didn't pass all authorisation for interception would have ceased as the previous regime expired. I thought that was a price worth paying; he didn't. He was properly scathing about the process, though.
