The thing that worries me most now about Boris's lies and Partygate is the acceptance by significant numbers of the British people.
The reaction of many on phone-ins and social media is "I'm bored of the story", "I'm over it", "there are far more important things in the news we should be focusing on". It's like they are now tolerant of a serial liar in charge of the nation. Day by day, Boris is dragging the nation's standards down so that what people find acceptable in a leader is basically turning up for work and telling them what they want to hear.
It's like a parent - who had previously stuck to guidelines - caving in while their kids do what they want, when they want, all the time. In Britain we had political standards that were more rigorous than those of those countries, and that gave us some sort of stable democracy and framework for government and accountability. That seems to be going out the window. Once gone, it is hard to re-establish.
...and that is the point. Most people are unwilling to accept being lied to, whatever their pov.
