Why not? I mean, that Johnson is a liar is indisputable.
I don't care about lies in Boris Johnson's private life and certainly not from 10, 20, 30 years ago - John Major covered up an extramarital affair for four years. 'Political spin' or 'misremembered facts' I don't consider 'lies'.

That handing government contracts to mates via private channels is corrupt.
Which contracts in particular? Where would you have sourced PPE from considering only 1% of the UK's PPE was manufactured domestically at the time?
That discharging positive cases to care homes was (at best) incompetent.
I think it was established by Dominic Cummings that Boris Johnson was not aware of this at the time. Most hospital trusts claimed they did test in any case, asymptomatic transmission caught everyone by surprise, and there is little evidence that the discharges directly led to any deaths. Most infections were probably spread around care homes by agency staff moving from home to home, staff being assigned to Covid/suspected Covid residents and non-Covid residents at the same time, staff not self-isolating (possibly because they were not paid/couldn't afford to self-isolate or they were asymptomatic) and staff mixing during their rest/lunch breaks. Germany has had thousands of care home infections and deaths over the course of the pandemic - how did the infections get in?
