A rather tantalising (if putative at the moment) prospect may be on the cards, should John Bercow decide to stick by his avowed intent to give up the Speakership after 9 years (which would be in 2018). The bookies have 2 main favourites, as outlined here (from The Fail - sorry):
http://www.dailymail.co.uk/news/article-4121034/Etonian-Brexiteer-Jacob-Rees-Mogg-versus-firebrand-ex-priest-Chris-Bryant-battle-Commons-Speaker.html There's also this local view of the matter:
http://www.bristolpost.co.uk/could-jacob-rees-mogg-mp-be-the-next-speaker-of-the-house-of-commons/story-30062435-detail/story.html The current senior Deputy Speaker, Lindsay Hoyle, is a distant third in the betting.
But then again, John Bercow may decide to stay put....
