Critics of her measure have raised fears of coercion and a slippery slope to wider legislation taking in more people.

But the virtual safety car turned into a full one, and then as that led the field around, a red flag, when Williams’ Franco Colapinto became the latest of several drivers to crash in the slippery conditions.

The Archbishop of Canterbury Justin Welby told the BBC that legalising assisted dying was "dangerous", and could lead to a "slippery slope" where more people would feel compelled to have their life ended medically.

He says it could be caused by fallen leaves "or sometimes you get very strange combinations of mist and rain that can end up creating a bit of an oily surface on top of the rail head and that’s extremely slippery".

He has also spoken of concerns about a "slippery slope" - which Archbishop of Canterbury Justin Welby has also warned of.
