UK Parliamentary by-elections, 2015 onwards (also devolved legislatures)

Perhaps it's just me, but it seems like a lot of British MPs die. In the last Parliament, 6 did.

Ah, civilized countries where politicians resign from Parliament when elected mayors. Is it by law, and is it for every mayor office, or just the largest ones ?

It's not a law at all, and Boris Johnson was an MP and Mayor of London from the 2015 election on. Most Mayors in the UK aren't directly elected, either.

I thought that once a Hereditary Lord died, then the election would be about selecting a formerly kicked out family of Lords and inviting one of them back into the House? It seems terribly complicated.
