While I haven't read What Not I have read the other novel mentioned here, We by Yevgeny Zamyatin and I have to say 1984 pretty much completely takes the entire plot from it. Spoilers follow: Both books follow the journey of a single man as he has a romance with a rebellious woman, get involved with a rebellion but then find out that an older man who they thought they could trust was really part of the secret police. Both novels end with the protagonist getting brainwashed and once again loyal to the state. While I like and respect Orwell immensely as an author, it's clear that he owes a great debt to Zamyatin for his most famous novel.
