Bookmakers and betting exchanges regulated in the UK have always been pretty careful about not adding unlawful markets.
Anything that relies directly or indirectly on the death of a real person is covered outlawed by the Life Assurance Act, so you've never been able to bet on things like fatal crashes in an F1 race or the date of the start of the next monarch's reign.
