We live in the age where populism is King, but ironically it's coming from wealthy elite types that are just slowly pushing more and more to see what bullshit they can get away with. The first example in recent times was when the financial crisis, caused by a handful of bankers, resulted in catastrophic results as people - poor and rich alike - lots their jobs and found their public and private services diminished. These same people were told "no, the bankers who caused the crisis aren't to blame it's benefit scum and illegal immigrants" and once it became clear that people were lapping it up they must have rubbed their hands together and thought "feck me, what else can we get away with?"
What was once scandalous has slowly become normal, and the default response to anything that could kill a political career is to lie. And if you somehow manage to get caught and your management of media and public opinion isn't strong enough to stop a mountain of allegations to come your way, you simply just ignore it until it goes away.
Let's face it; Boris will win any election that comes up, the UK will be slowly sold off and fecked even more but nothing will change for the better in our lifetimes because they've already fecking won.
