We need to bring them down with a bump to our level. We must remind them that they are there to do a job, on our behalf, for our good, and only because we asked them to. I can highlight the current level of unaccountable government by telling a hypothetical story. A fascist party in the near future is elected to Westminster because of manifold economic problems and social stresses caused as a result. They implement extremely radical and right-wing policies.
Reasonable people see what they are, but it is too late.
One slip by the electorate at a bad time has condemned the country to autocracy. Well - there is no Bill of Rights, or written constitution, so they are not actually breaking any rules. The judiciary is politically appointed, so it is not independent enough to act. The Queen, as Head of State, may try, but this will only create a constitutional paradox, and destroy the monarchy. The House of Lords cannot overrule the Commons, because it is unelected.
