There’s some good quotes on wikiquote en.m.wikiquote.org/wiki/Boris_Johnson
I especially like
Interviewer: Can you give an example, in your political life, when you've set your own self-interest aside for the benefit of the country?
Boris Johnson: Well, er, pfft, um, it's a good question, but er, I, I, I would, you know, I don't, obviously, it's an embarrassing but, but true that, um, er, it is obviously, possible, er, how should I put this, to make more money, er, by not being a full-time politician. Um, I don't, I don't want to put too finer point on it, er, but, you know, you have to, you have to, you have to, make sacrifices sometimes.

And quotes about him
90,000 Conservative members, whose views have become more extreme as their numbers have fallen, recently selected Boris Johnson as their new leader, and thus as the country's new prime minister. In doing so, they have chosen a mendacious chancer. It is no exaggeration to say that Johnson has lied his way to the top, first in journalism and then in politics.
Chris Patten, former chairman of the Conservative Party, writing in an opinion column entitled "Is Britain Becoming a Failed State?" (20 August 2019)
And a letter to him
I am surprised and disappointed that you have chosen to repeat the figure of £350 million per week, in connection with the amount that might be available for extra public spending when we leave the European Union. This confuses gross and net contributions. It also assumes that payments currently made to the UK by the EU, including for example for the support of agriculture and scientific research, will not be paid by the UK government when we leave. It is a clear misuse of official statistics.
