He's history

Alexander Boris de Piffel Johnson is a lair.

He mislead the Commons on 8 (eight) occasions.

He mislead the Standard's Committee a further 11 (eleven) times.

The 90 day suspenstion form the House was greatly increased due to his personal attacks on members of the committee.

He pass to the Palace of Westminster, one that all ex-MPs get, has been revolked for life. Meaning the role of a lobbiest is now closed to him.

Johnson lied at the dispatch box and failed to correct the record at the nearest opportunity.

This we know as only 7 (seven) MPs voted against the report from the committee. That being said, almost all of the Conservative benches were empty, including the PM himself, many Ministers attended a Coservative Home summer ball instead of attending the Commons.

So much then for a new era of high standards and morals.

Can Johnson come back?

No one Parliament can bind a subsequent one, and a future Conservative Government could admit him into the party, even as an MP, but unclear whether the pass would prevent him carrying out his duties. That is certainly the case if he were to stand and win as an independant.

Johnson was not sanctioned for "partygate" or attending any gatherings. He was sanctioned for misleading the House. And who saw that the former journalist and MP twich sacked for lying or making up quotes would turn out to lie in the Palace of Westminster?

Just about everyone, of course. But because like Trump with the GOP, the Tories held their noses and went along with a "winner", until he stopped being a winner.
