While it fails to register with the likes of you that they DO have a say in how the country is run, they can vote out any MP they want to, they have the right to demand a trial by a jury of their peers in a capital offence, they can take civil matters to the queens bench as a right.
The Hillsborough verdict as an example would not have been possible in any other EU country because the state makes the decision and thats the end of the matter.
The "Overwhelming" majority of MPs are also a bunch of self serving c*nts are they not ?, they know full well that getting out of the EU curtails their gravy train ride if they get voted out for following the party line rather than representing the wishes of the electorate.
