The former House of Commons Speaker was found to be a “serial bully” who “repeatedly and extensively” berated staff by an independent expert panel.
The report concluded that if he was still an MP “he should be expelled”.
Mr Bercow unleashed a furious response to the findings.
In a statement, he said: “Parliament is supposed to be the highest court in the land. This inquiry, which lasted a ghastly 22 months at great cost to the taxpayer, has failed it dismally.
“At the end of it, the panel has simply said that I should be denied a parliamentary pass which I have never applied for and do not want. That is the absurdity of its position.
“Don’t fall for the establishment spin that I have been banned for life. I can still attend debates with the help of a friendly passholder or go as a member of the public.
“All I can say is that the case against me would have been thrown out by any court in the land since it is based on the flimsiest of evidence, rooted in hearsay and baseless rumour, and advanced by old school dogmatists once intent on resisting change at all costs and now settling some ancient scores with me. Add to that a dash of personal spite and you have some idea of the vengeful vendetta mounted against me.
“It is a travesty of justice and brings shame on the House of Commons.
“This has been a protracted, amateurish and unjust process which would not have survived five minutes’ scrutiny in court. To describe what I have experienced as a kangaroo court is grossly insulting to kangaroos. None of the investigators is a lawyer and the commissioner overseeing them has no expertise whatsoever in the consideration of alleged bullying.
“Throughout, gossip from absent friends of the complainants has been treated as the absolute truth whilst eyewitnesses who challenged the allegations were described as ‘not helpful’ and discounted. The commissioner even presumed to make findings on matters about which I was never questioned.”
