I doubt there was ever a PM who didn’t lie about something. They are human, and it would be a miracle if they got through their years in office without having to bluff their way through some dodgy decision or other. The problem is, there were too many sharks wanting Boris’s downfall so his lies were exposed and blown up out of proportion.
If it had suited them not to expose him, we’d never have known a thing…and really, he had a lot more to deal with (Brexit, pandemic, the economy, war) than how long he was at a party or who was feeling somebody’s ass (does the government not have an HR department to deal with complaints like this?)
