Revoke, set rules for all further polls, make mp's sign an oath of honesty in order to make prosecution inevitable for Deliberate LIES (under the umbrella of treason law), remove the media from the safety of "free press immunity", after all they created this nightmare, their owners must pay the price for their naked manipulation of the public.
Whilst the country is marching backwards under FPTP the media ensures this happens as they effectively run the country, and not in some surreal tory propaganda way that the "unions were running the country", but in a very real way by Lying, twisting spinning public opinion. The UK is in the grip of a handful of far-right billionaires and the rump of thatcher supporters that just put bojac in Downing street. They have no credible opposition, again thanks to the partisan media.
You know you really are in the brown stuff when trump endorses the new PM...
