There could be a fanfic where the Prime Minister discovers he has some latent magical ability due to his close association with the wizarding world. In this story, he could start learning basic spells and charms, all while trying to keep it a secret from the public. This would add an interesting twist to the typical relationship between the Muggle and wizarding worlds.
One interesting fanfiction could be where the Prime Minister has to deal with a magical crisis in the Muggle world that is somehow connected to Hogwarts.

Another theme is the discovery of the wizarding world by the Muggle Prime Minister. This often involves a sense of wonder and confusion as he is exposed to things like magic spells and magical creatures.

I'm not sure specifically if there is a well - known 'Harry Potter is the Prime Minister' fanfiction. But given the vastness of the fanfiction community, it's entirely possible. Fanfiction allows for all kinds of crossovers and alternate universes. So, someone might have written a story where Harry Potter, with his magical abilities and heroic nature, steps into the role of the Prime Minister to solve both magical and non - magical problems in a unique way.
Perhaps the Muggle Prime Minister is accidentally affected by a spell that makes him see magical creatures everywhere. He then has to deal with the chaos while also trying to keep it a secret from the public. He might start to question his own sanity until a wizard comes to his aid.
Well, one possible plot could be that Harry uses his magic to combat various threats to the country that normal politicians can't handle. Like using spells to stop terrorist attacks or natural disasters. He might also have to hide his magic from the public while still using it for the greater good.
One possible plot could be that the Prime Minister has to seek help from the wizarding world led by Harry Potter to deal with a dark magic threat that is seeping into the Muggle world. For example, strange magical creatures are starting to appear in London and causing chaos. Harry Potter and his friends then work with the Prime Minister's office to figure out a way to send these creatures back to their proper magical realm and also put up wards to prevent further incursions.
In this fanfiction, it could be that the prime minister has to work with Harry Potter to prevent a wizard from using magic to influence political decisions. Harry, with his knowledge of the wizarding world, would be the key to uncovering the plot. They might have some initial misunderstandings due to their different worlds, but eventually learn to cooperate. The prime minister could be amazed by the magical creatures Harry introduces to him, like a hippogriff or a phoenix, which would be a completely new experience for him.
One interesting 'Harry Potter' fanfic could be those that explore different relationships between the characters. For example, a fanfic might focus on the friendship between Harry and Neville in more depth, showing how they support each other in ways not fully explored in the original books. Another could be a time - travel fanfic where a character goes back in time to change certain events in the wizarding world. There are also fanfics that might give more backstory to minor characters like Luna Lovegood, making her character even more fascinating.
One interesting fanfic could be those that explore James Potter's time at Hogwarts before Harry was born. It might show his adventures with his friends, like Sirius and Remus.

There might be fanfics that focus on the backstories of minor characters. In 'hell harry potter fanfic', perhaps there are stories about the life of a house - elf we barely knew in the original books, like Dobby's early years at the Malfoy Manor.
