Harry Potter author JK Rowling is fed up with Jeremy Corbyn supporters comparing the Labour leader to one of her most famous characters.

Supporters of Corbyn have called him a "socialist version" of the magical headmaster Dumbledore. Both men have white facial hair — but Rowling said that's where the similarity ends.

Rowling tweeted "Corbyn. Is. Not. Dumbledore" to her more than 8 million followers, linking the tweet to an article on Corbyn's paid appearances on the Iranian news channel Press TV which was banned in the U.K. for its part in filming the detention and torture of a journalist.

This isn't the first time she has criticized comparisons between Corbyn and Dumbledore, once tweeting: "I forgot Dumbledore trashed Hogwarts, refused to resign and ran off to the forest to make speeches to angry trolls."

Despite Rowling's insistence, Twitter still didn't seem convinced of her argument.
