whose knowledge of British Parliamentary systems are limited to John Bercow and watching BoJo's antics.

From Wikipedia:

The 1922 Committee, formally known as the Conservative Private Members' Committee,[2] is the parliamentary group of the Conservative Party in the House of Commons of the United Kingdom. The committee, consisting of all Conservative backbench members of Parliament, meets weekly while Parliament is in session and provides a way for backbenchers to co-ordinate and discuss their views independently of frontbenchers. Its executive membership and officers are by consensus limited to backbench MPs, although since 2010 frontbench Conservative MPs have an open invitation to attend meetings. The committee can also play an important role in choosing the party leader.

Oh, yeah, remember John Bercow?

I try not to leave people hanging if I make an obscure reference. I know a lot about many things that would leave people gasping. It doesn't mean it makes me smarter.
