Why does anyone - whatever their political persuasion - put themselves forward for this role? You have to be in London for extended periods, often leaving your family behind. The money is good but many of them could earn a lot more doing other stuff. You get death threats and abuse on a daily basis. When you're at your workplace and stand up to speak, you get boos and heckles from the people sitting opposite you. You have no job security.You have to read unpleasant stuff about yourself or hear people commenting about you, your party or the political system in general.
The whole thing seems to me to be a total nightmare and the most toxic working environment imaginable. No wonder so many of them are not standing for re-election.
