Protest not just in London, outside front benchers' houses and the tax supplied homes they use when allegedy "working". Fear purveyed by liars, thieves, murderers and pervert politicians in Parliament and imbued in the public by controlled media has to be eliminated from society. Nuclear wars, globalwarming, terrorism (I've never seen a terrorist in real life), overpopulation, Russia, currency collapse etc. All fake except for nuke wars and currency collapse that are pre-tested by fake alarms until the people that control the political pork partakers decide otherwise.
The only way any government serves the public is if the fear is returned to the side of the oppressors that steal your hard earned curency in too many ways to list and sell off public assets so they can be bought back for a profit to the purchaser.

Get Cameron on a lie detector. Ask him how much of the electorate he serves. The true answer is the 0.0001%.
