[Harry Potter] Does the Wizarding World offer magical protection to the Muggle World's leaders?

Its been implied in the books that the highest echelons of muggle society (Royalty, Prime Ministers, etc.) Are aware of the existence of magic and of the Wizarding World. If that is the case, than does the Ministry of Magic offer magical bodyguards, protections, or advisors to World Leaders like, say, The Queen of England or the Prime Minister? What sort of magical precautions would be used? And is there an active threat of a rogue wizard or witch trying to kill a Muggle World Leader?

The Ministry does assign protection to the Muggle Minister of Magic during times of crisis. Kingsley Shacklebolt went undercover as an aide to the Muggle Minister in *The Halfblood Prince*. It’s unknown if this protection is also extended to the Royal Family but presumably it is, because their sudden deaths would attract unwanted attention. 

It’s somewhat unclear if the Ministry is Magic *always* has Aurors assigned time Muggle leaders or only during times of conflict, or only during extraordinary circumstances. Voldemort and Grindelwald’s wars were certainly extraordinary circumstances because they directly involved attacks in the Muggle world - in the films, the Death Eaters destroyed Millennium Bridge and it’s implied that the caravan park was destroyed by Death Eaters; in the books, random Muggles get attacked and the Muggles start to suspect that something is amiss.
