Well, if we in the UK are some how responsible for Euro spying on behalf of our US masters, then presumably GCHQ is the centre for all spying on all US citizens who come to Europe. I kinda think its almost a silly question. Of course we are, we are just waiting for the relevant leak to confirm it. UK wise, I reckon its possibly more worthwhile to ask about GCHQ spying on MP's, UK MEPs, and members of the House of Lords. However, we actually do know that UK security services do spy on elected officials as we know a hell of a lot about what they got up to in Norther Ireland. IIRC, Americans were historically critical of how we treated Irish freedom fighters..... or was it terrorists? But were mainland British folk concerned because they spied on Northern Irish politicians? Not that I know of. Then look at the reaction of British politicians to the Snowden leaks. Pretty muted. Again, I suspect that they are kept in line by implied blackmail. What might be vaguely useful is if we had a set of standard well formatted questions, that people can copy and use to send to our MPs.
