The Commons Privileges Committee sure as hell did (think he lied), following their investigation in to Johnson’s behaviour; although they used the parliamentary language of ‘deliberately misleading the commons’ – rather than lying.

Read the Committee's report.

This is the Committee's report, https://publications.parliament.uk/pa/cm5803/cmselect/cmprivi/564/summary.html

The damning Privileges Committee report in to Johnson’s lies is not very long, if you care to take a read.

It's long enough, and as far as I read seems to assume rules had been broken, something which had been denied, and most likely is simply down to interpretation.  No, I don't intend to read it all.

'The damning Privileges Committee' was as fake as its report.  

he said that covid rules had been followed in no.10 when he knew for sure that they hadn't

In his opinion they had. 

Having read the report they seemed to have gone out of their way to prove him guilty. They even visited the place where the "offence" took place, juries sometimes do that in a murder trial but was it necessary in this case?

It was in effect a murder trial, Vulcan, the outcome pre-arranged.

When news of BJ's affair with Petronella Wyatt broke, he said the reports of an affair were an "inverted pyramid of piffle." But when the reports were proven, he was sacked as Shadow Arts Minister.

At the time, Con Leader Michael Howard said it was a question of personal morals and that BJ had been dismissed because he had lied about the affair.

the "opinion" defence isn't plausible.

In addition, there will have been numerous occasions when he lied to whichever partner he was wth at the time, in order to continue with his multiple extra-marital affairs.

And, if he is capable of lying to whoever he supposedly loves the most (apart from himself, of course), then lying to the country wouldn't phase him at all.

i mean that in the case of boris johnson it isn't credible to suggest that he thought the rules were being followed
