In addition to the election for London Mayor, there are elections to the London Assembly, which use the same voting system as the Scottish Parliament, but for some reason London-based journalists seem to think that the Scottish system is unfathomably complicated and alien, while the London system is, I dunno, a tombola.
There are constituency elections, which are mostly two or three Boroughs squished together; and then the London-wide "top up" to bring proportionality into it.
I won't recreate the entire London-wide "top up" ballot paper here (you can find it at this link -
