In the U.K. the Speaker of the Lower House of Parliament has several duties. Some of these have been hazardous to their health:
The Speaker sets the agenda for debate in parliament, calls on members of parliament to speak, can limit question time and decide whether amendments should be voted on.
They also traditionally serve as a liaison with the monarch, acting as a buffer between the Commons and the sovereign.
In the past, when relations between the two were not always so good, Speakers had a deadly job. In fact, nine Speakers, all prior to 1560, died a violent death, one murdered, one killed in battle and seven beheaded, two on the same day.
I’m all for our Speaker of the House Nancy Pelosi resigning because of her scandal (as the U.K. speaker is) but being beheaded seems a little over the top (as well was being a little off the top).
