There's a lot of rubbish talked about traditions and conventions when it comes to electing of a new .
First, it's said it's conventional to elect a Speaker mid-term, so that he or she is elected entirely by people who know him rather than brand new MPs, and that it would therefore be a breach of that rule.
Second, it's said it's conventional for the Speakership to alternate between the two main parties, and that election in 2000, as a second successive Labour Speaker, following , was a breach of this rule.
But a quick look at the post-war Speakers shows these rules don't really exist:
1943-1951 Douglas Clifton Brown (Con)
1951-1959 William Morrison (Con)
1959-1965 Sir Harry Hylton-Foster (Con)
1965-1971 Horace King (Lab)
1971-1976 Selwyn Lloyd (Con)
1976-1983 George Thomas (Lab)
1983-1992 Bernard Weatherill (Con)
1992-2000 Betty Boothroyd (Lab)
2000- Michael Martin
Five of the above nine Speakers - Clifton-Brown, King, Lloyd, Thomas and Martin - were indeed elected mid-term, though in King's case this was because the previous Speaker died in office.
But four others - Morrison, Hylton-Foster, Weatherill and Boothroyd - were elected at the start of a Parliament. So that's hardly a hard and fast rule.
And eight of the nine post-war Speakers were elected when their party was the biggest in the House.
The only exception was Betty Boothroyd when the Conservatives had a small majority.
