As far as I know, from having observed the British Press, Boris was mostly a liar about his personal conduct and behavior and keeping promises he made or successes he thought he was responsible for (and about his administration's spending and "professionalism and competency), but was not known for fabricating about foreign policy or the statements or actions of foreign officials. So he lied about parties, drinking, his own sex life, etc. and what "Good" he thought Brexit had brought to Britain (when it brought no good at all). Pretty much the worst of recent British Politicians, but still better than the deranged babblings of Trump.

But going thru all the falsehoods can take a while and I may have missed a few. .

Lies, Falsehoods and Misrepresentations from Boris Johnson to Rishi Sunak.

I am used to taking people by the name they identify, just as I do by the pronouns they choose. My wife changed her name from the one she was given at birth long before I met her (she was handed a ‘family name’ originally which did not in any way suit her, to honor someone else’s religious beliefs that she does not follow), and instead has a name that there are only a handful of people have in the country with.

So, he can be Boris if he wants to, it doesn't matter to me. He could be John Johnson if he wants to, just so we have a unique identifier to hang his actions, Lies or Starbucks orders to.
